Printer features are accessed through the corresponding commands of Hewlett-Packard's PCL language. This manual describes the PCL 5 printer language. This includes descriptions of the commands available for Hewlett-Packard PCL 5 LaserJet printers and the basic requirements of PCL language programming. With the release of new LaserJet family printers there are new features added which supplement the existing PCL base set. Features of future printer releases are not covered in this document. The new features are described in the latest version of the PCL 5 Comparison Guide. Programmers should familiarize themselves with the information provided in the PCL 5 Comparison Guide in addition to the information in this document. Experienced Users This manual was written for people with some programming experience. Many of the concept discussions assume some programming knowledge. When writing a PCL language program, you should know the PCL language concepts and commands presented in this manual, and should be aware of the differences in implementation of the PCL 5 printer language for the various HP LaserJet printers, as described in the PCL 5 Comparison Guide. Non-technical Users Many software applications (word processing software, spreadsheets, etc.) allow you to embed printer commands as escape sequences in the body of your documents. This manual presents the full syntax and explanation of all the commands supported by PCL 5 LaserJet printers. These commands enable you to take advantage of the LaserJet printer's advanced feature set. EN v Note Since actual implementation of printer commands within software applications varies from package to package, specific examples are not given. For examples of printer command usage with many popular software packages, refer to HP's Software Application Notes, provided with the printer. The most current versions of software application notes can be obtained through the HP Forum on CompuServe, by fax using the HP FIRST fax service, or through HP's literature distribution. Refer to Appendix A for more information. Chapter Summaries A brief description of each chapter is provided below. Chapter 1 - Introduction to HP PCL This chapter gives a brief history of the development of the PCL language, describes the PCL language levels (architecture), and describes the PCL command structure (control codes and escape sequences). Chapter 2 - The Page This chapter introduces the idea of the logical page and identifies the area in which printing can occur. It also describes the PCL coordinate system and the HP-GL/2 picture frame. Chapter 3 - The Print Environment This chapter introduces the printer's feature settings, collectively, as the print environment. It includes descriptions of the factory default environment, user default environment, and the modified print environment. The effect of printer reset functions is also described. Chapter 4 - PCL Job Control Commands This chapter describes the commands which provide job control. Job control commands are usually grouped together and sent at the beginning of a job. Job control includes restoration of the User Default Environment, selection of the number of copies of each page to be printed, duplex print commands, and unit of measure specification. vi EN Chapter 5 - Page Control Commands This chapter describes the commands providing page format control. Page format control allows you to select the page source, size, orientation, margins, and text spacing. Chapter 6 - Cursor Positioning This chapter describes how to position the cursor within the logical page. Chapter 7 - Fonts This chapter describes basic font information including font characteristics. Chapter 8 - PCL Font Selection This chapter describes how to select a font for printing using the font characteristics commands. The underline feature is described at the end of the chapter. Chapter 9 - Font Management This chapter describes font management which provides mechanisms for downloading and manipulating soft fonts. Chapter 10 - User-Defined Symbol Sets This chapter describes the capability of some PCL 5 printers to enable users to define their own symbol sets for special needs. Chapter 11 - Soft Font Creation This chapter describes how to organize font/character data for downloading to the printer. Chapter 12 - Macros This chapter describes macro commands which store a block of PCL commands and data which can be used repeatedly without redefining the block. The macro function reduces the number of commands that must be sent to the printer. EN vii Chapter 13 - The PCL Print Model This chapter describes the PCL print model which allows for special effects when printing. Chapter 14 - PCL Rectangular Area Fill Graphics This chapter describes how to define and fill a rectangular area with one of the predefined PCL patterns, or with a user-defined pattern. Chapter 15 - Raster Graphics This chapter describes how to download raster graphics to the printer, and includes various techniques for reducing the amount of data needed to define the raster image. Chapter 16 - Status Readback This chapter describes the PCL status readback features. Status readback enables you to obtain PCL status information from the printer, such as: available printer (user) memory, a list of fonts and symbol sets, and the ID numbers of macros and user-defined patterns. Chapter 17 - An Introduction to HP-GL/2 Vector Graphics This chapter introduces basic information for HP-GL/2. It lists the vector graphics commands, and describes the HP-GL/2 command syntax. An overview of several important topics is also provided, such as the PCL Picture Frame concept, scaling, pen status and location, and absolute vs. relative pen movement. Chapter 18 - The Picture Frame This chapter describes how to set up an area on the page for printing vector graphics (the PCL Picture Frame). It discuses the commands necessary to define and position the picture frame, along with the commands used to enter and exit HP-GL/2 mode. viii EN Chapter 19 - The Configuration and Status Group This chapter describes the commands used to set default conditions and values for programmable HP-GL/2 features. It also explains the commands used for scaling, establishing a soft-clip window, and rotating the HP-GL/2 coordinate system. Chapter 20 - The Vector Group This chapter provides information about pen movement and drawing lines, arcs, and circles. It also covers a way to encode coordinates for increased print speed. Chapter 21 - The Polygon Group This chapter explains the polygon mode and how it is used to draw polygons, subpolygons and circles. The commands for drawing and filling wedges and rectangles are also described in this chapter. Chapter 22 - The Line and Fill Attributes Group This chapter describes the commands used to vary the line types and fill patterns used to create HP-GL/2 graphics. Chapter 23 - The Character Group This chapter contains information about the commands used to print text (labels) in HP-GL/2 mode. This allows you to print HP-GL/2 labels in almost any size, slant and direction using proportional or fixed-spaced scalable fonts. Chapter 24 - Programming Hints This chapter provides programming information for use during the development of PCL software.

Customer Support-1 Index EN Contents-13 Contents-14 EN 1 Introduction to HP PCL PCL PRINTER LANGUAGE HISTORY Hewlett-Packard created the PCL printer language (simply referred to as "PCL" elsewhere in this manual) to provide an economical and efficient way for application programs to control a range of printer features across a number of printing devices. HP has evolved both the definition and implementations of PCL to provide the optimal price and performance balance. PCL 5 represents a new breakthrough in price/performance leadership. Its features were selected in direct response to customer requests. HP will continue to lead enhancements to the PCL printer language to deliver powerful technology advances. PCL commands are compact escape sequence codes that are embedded in the print job data stream. This approach minimizes both data transmission and command decoding overhead. HP PCL formatters and fonts are designed to quickly translate application output into high-quality, device-specific, raster print images. PCL printer language commonality from HP printer to HP printer helps to minimize printer support problems and protect HP printer customer investment in applications and printer driver software. EN PCL PRINTER LANGUAGE HISTORY 1-1 PCL Printer Language Architecture PCL printer language structure has been useful to guide language functionality growth and command syntax definition. The PCL printer language has evolved through five major levels of functionality driven by the combination of printer technology developments, changing user needs, and application software improvements. The five phases of the PCL printer language evolution are: PCL 1 Print and Space functionality is the base set of functions provided for simple, convenient, single-user workstation output. EDP (Electronic Data Processing) /Transaction functionality is a superset of PCL 1. Functions were added for general purpose, multi-user system printing. Office Word Processing functionality is a superset of PCL 2. Functions were added for high-quality, office document production. Page Formatting functionality is a superset of PCL 3. Functions were added for new page printing capabilities. Office Publishing functionality is a superset of PCL 4. New publishing capabilities include font scaling and HP-GL/2 graphics. PCL 2 PCL 3 PCL 4 PCL 5 The PCL printer language model succeeds because the following points are observed: All HP LaserJet printers implement PCL printer language features consistently. HP printers implement the above language feature groups in very cost-effective formatters. HP printers have the ability to ignore most unsupported commands. 1-2 Introduction to HP PCL EN What are Printer Commands? PCL printer commands provide access to printer features. There are four general types of HP printer language commands: control codes PCL commands HP-GL/2 commands PJL commands Control Codes A control code is a character that initiates a printer function, for example Carriage Return (CR), Line Feed (LF), Form Feed (FF), etc. PCL Commands PCL commands provide access to the printer's PCL control structure. The PCL structure controls all of the printer's features except those used for vector graphics, which are controlled by the HP-GL/2 commands. PCL printer commands consist of two or more characters. The first character is always the ASCII escape character, identified by the ? symbol. ? is a special control code which identifies the subsequent string of characters as a printer command. As the printer monitors incoming data from a computer, it "looks" for this character. When this character appears, the printer reads it and its associated characters as a command to perform and not as data to print. Note PCL printer commands (other than single-character control codes) are also referred to as escape sequences. The terms printer command and escape sequence are used interchangeably throughout this manual. Once a PCL command sets a parameter, that parameter remains set until that PCL command is repeated with a new value, or the printer is reset to its user default environment. For example, if you send the printer a command to set line spacing to 3 lines/inch, each page prints 3 lines/inch until the printer receives a different Line Spacing command, or the printer is reset. EN What are Printer Commands? 1-3 HP-GL/2 Commands HP-GL/2, vector graphic commands are two letter mnemonic codes designed to remind you of the function name (such as IN for Initialize). Following the two letter mnemonic may be one or more parameters, which identify details of how to process the command. For additional information on HP-GL/2 commands, refer to Chapters 17 through 23. PJL Commands PJL (Printer Job Language) commands provide a different type of printer control. Unlike PCL and HP-GL/2, which control the placement of dots on the printed page, PJL supplies job-level control. One of the main features PJL offers is the ability to switch printer languages (personalities) between jobs. For example, applications supporting PJL can print one job using PCL, and then print the next job using PostScript or another printer language, without any operator intervention. PJL also provides two-way communications with the printer. For example, PJL can request information from the printer such as printer model, configuration, printer status, and job status. PJL also can be used to change the printer's control panel settings and modify the message displayed on the control panel. The PJL language is designed to be used by application developers and technical support personnel only. 1-4 Introduction to HP PCL EN Syntax of Escape Sequences There are two forms of PCL escape sequences: two-character escape sequences and parameterized escape sequences. Two-Character Escape Sequences Two-character escape sequences have the following form: ?X where "X" is a character that defines the operation to be performed. "X" may be any character from the ASCII table within the range 48-126 decimal ("0" through "~" - see Appendix A). For a list of the two-character escape sequences supported by the printer, refer to the "PCL Feature Support Matrix" in Chapter 1 of the PCL 5 Comparison Guide. Following are examples of two-character escape sequences: ?E ?9 a two-character escape sequence used for resetting the printer. a two-character escape sequence used for resetting the left and right margins to the printer's default settings. EN Syntax of Escape Sequences 1-5 Parameterized Escape Sequences Parameterized escape sequences have the following form: ? X y z1 # z2 # z3 ... # Zn[data] where y, #, zi (z1, z2, z3...) and [data] may be optional, depending on the command. X Parameterized Character - A character from the ASCII table within the range 33-47 decimal ("!" through "/") indicating that the escape sequence is parameterized. Group Character - A character from the ASCII table within the range 96-126 decimal (" ` " through " ~ ") that specifies the group type of control being performed. Value Field - A group of characters specifying a numeric value. The numeric value is represented as an ASCII string of characters within the range 48-57 decimal ("0" through "9") that may be preceded by a "+" or "--" sign and may contain a fractional portion indicated by the digits after a decimal point (" . "). Numeric value fields are within the range -32767 to 65535. If an escape sequence requires a value field and a value is not specified, a value of zero is assumed. Parameter Character - Any character from the ASCII table within the range 96-126 decimal (" ` " through " ~ "). This character specifies the parameter to which the previous value field applies. This character is used when combining escape sequences. Termination Character - Any character from the ASCII table within the range 64-94 decimal (" @ " through " ^ "). This character specifies the parameter to which the previous value field applies. This character terminates the escape sequence. Binary Data is eight-bit data (for example, graphics data, downloaded fonts, etc.). The number of bytes of binary data is specified by the value field of the escape sequence. Binary data immediately follows the terminating character of the escape sequence. y # zi Zn [data] 1-6 Introduction to HP PCL EN The following is an example of an escape sequence with a termination character and no parameter character. This escape sequence performs a single function. Notes Some escape sequences shown in this manual contain spaces between characters for clarity. Do not include these spaces when using escape sequences. Also, in the escape sequence a script "l" is used to indicate a lower case "l" for clarity. The following is an example of an escape sequence with a parameter character and a termination character. This escape sequence performs two functions. It is the combination of two commands (?&l1O and ?&l2A): Notice that the "?"and the "&l"are dropped from the second printer command when the two commands are combined. Also, the upper-case "O" that terminated the first command becomes a lower-case "o" parameter character when these commands are combined. EN Syntax of Escape Sequences 1-7 Use these three rules to combine and shorten printer commands: 1 The first two characters after "?" (the parameterized and group character) must be the same in all of the commands to be combined. In the example above, these are "&" and "l". All alphabetic characters within the combined printer command are lower-case, except the final letter which is always upper-case. In the combined example above, "O" becomes "o". The final character in the printer command must always be upper-case to let the printer know that the command is complete. The printer commands are performed in the order that they are combined (from left to right). Be sure to combine commands in the order that they are to be performed. 2 3 1-8 Introduction to HP PCL EN 2 The Page Introduction This chapter describes the PCL coordinate system. It defines the logical page and the printable area; it introduces the HP-GL/2 (vector graphics) picture frame, and identifies the boundaries of each. EN Introduction 2-1 Logical Page The PCL logical page (also referred to as the PCL addressable area) defines the area in which the PCL cursor can be positioned. Although the printer does not actually have a cursor (like the blinking underline character used on most computer terminals), the cursor position refers to the Currently Active Position of the cursor (also referred to as the CAP). The location of the "cursor" is the position on the logical page where the next character will be positioned. The cursor can be moved to different points on the logical page using the cursor positioning commands (see Chapter 6, Cursor Positioning). The PCL cursor cannot be moved outside of the logical page bounds. The size of the logical page for the media (paper, transparencies, labels, etc.) is defined in Table 2-1 and Table 2-2. 2-2 The Page EN Printed Dots The high quality output achieved by HP LaserJet printers is due in part to the ability to lay down a fine grid of "dots" on the page. The density of this grid is referred to as the printer's resolution. From the first HP LaserJet (the "LaserJet Classic") until recently, all HP LaserJet family printers printed at a resolution of 300 dots-per-inch. In a one inch square, the printer could print a dot anywhere in a grid of up to 300 dots horizontally by 300 dots vertically, for a total of 90,000 possible dot locations per square inch (300 × 300 = 90,000). The LaserJet 4 printer is capable of printing at either 300 or 600 dpi resolution. At 600 dots-per-inch, it becomes possible to print up to 360,000 dots per square inch (600 x 600 = 360,000). Print resolution of LaserJet 4 is selectable and can be specified either from the printer's control panel or programmed through PJL commands. Figure 2-1 300 vs 600 DPI Dot Sizes Note Refer to Appendix E of the PCL 5 Comparison Guide or the printer User's Manual to determine the default print resolution for a specific HP LaserJet printer. The printer's physical dot size has no direct bearing on the size of "PCL Units" used in cursor movements. PCL Units were previously referred to as "PCL dots", but should not be confused with the printer's physically printed dots. The size of PCL Units can also be specified (see the Unit of Measure Command in Chapter 4 for more information). EN Printed Dots 2-3 PCL Coordinate System The PCL coordinate system is defined as shown in Figure 2-2. Figure 2-2 X,Y PCL Coordinates The point (0,0) is at the intersection of the left edge of the logical page and the current top margin position. Note Since the point (0,0) is always at the intersection of the left edge of the logical page and the current top margin position, it moves if the top margin is changed, and rotates around the page if the orientation is changed. 2-4 The Page EN Units of the PCL Coordinate System The units of the X-axis of the PCL coordinate system may be PCL Units, decipoints, or columns. The units of the Y-axis may be PCL Units, decipoints, or rows. PCL Units These are user-definable units of measure which are used in PCL commands affecting various PCL cursor moves. The number of units-per-inch used in PCL cursor moves is determined by the current setting of the Unit of Measure command (see "Unit of Measure Command" in Chapter 4). Note PCL Units were formerly referred to as "PCL Dots". They were renamed "PCL Units" to prevent confusion with the printer's physically printed "dots", which are determined by the printer's resolution. Decipoints In PCL terminology, a decipoint is 1/720 inch or one-tenth of a PCL point (a PCL point is 1/72 inch as opposed to a typographic point which is 1/72 inch). Columns & Rows The width of a column is defined by the current horizontal motion index (HMI). The distance between rows is defined by the current vertical motion index (VMI), or lines-per-inch (lpi). HMI, VMI and lpi are described in Chapter 5, Page Control Commands. Printer Internal Units Internally, the printer uses a different unit of measure. It maps PCL Units, decipoints, and columns and rows to this unit of measure. This internal unit is 1/7200 inch. All positioning is kept in internal units and rounded to physical dot positions when data is printed. EN Units of the PCL Coordinate System 2-5 HP-GL/2 Picture Frame In addition to text and raster graphics, HP-GL/2 vector graphics can be placed on the PCL logical page. HP-GL/2 vector graphics are incorporated using the concept of the HP-GL/2 picture frame (see Figure 2-3). Within this picture frame, HP-GL/2 uses its own coordinate system and units of measure. The HP-GL/2 coordinate system and units are described in detail in Chapter 17, An Introduction to HP-GL/2 Vector Graphics, and Chapter 18, The Picture Frame. Note If no HP-GL/2 picture frame size is specified (using the commands described in Chapter 18), then the default HP-GL/2 picture frame is used. The default HP-GL/2 picture frame is the current top and bottom margins and the left and right edges of the logical page. The HP-GL/2 picture frame rotates with the PCL page orientation, but is not affected by the PCL print direction. Figure 2-3 PCL Logical Page with HP-GL/2 Picture Frame 2-6 The Page EN Printable Area The printable area is the area of the physical page in which the printer is able to place a dot. The physical page refers to the size of the media (letter, legal, etc.) installed in the printer. The relationship between physical page, logical page, default picture frame, and printable area is defined in Table 2-1 and Table 2-2.

When printing characters or graphics, if any portion of the character cell or graphic is outside the printable area, only that portion outside the printable area is clipped (see Figure 2-4). Figure 2-4 Printable Area Character Cell Positioning Notes Pixel level clipping can also occur at the logical page for PCL when the page is positioned using the Left Registration command. Pixel level clipping also occurs at the picture frame for HP-GL/2. Characters are clipped if they fall across a margin (left, right, top, and bottom). Refer to "Text Area" in Chapter 5 for additional information. EN Printable Area 2-9 2-10 The Page EN 3 The Print Environment Introduction The group of all of the printer's current feature settings, collectively, is referred to as the print environment. The printer maintains four print environments: the Factory Default Environment, the User Default Environment, the Modified Print Environment and the Overlay Environment. This chapter describes the Factory Default Environment, the User Default Environment, and the Modified Print Environment (the Overlay Environment is described in Chapter 12, Macros). Default settings refer to the settings programmed into the printer at the factory or settings selected using the control panel. The term "default" simply refers to the settings the printer uses unless printer commands select other settings. Each time a job is printed, some of the printer's feature settings may be changed from their default values to produce the desired printed output for that job. After the job prints, the job-specific feature settings are longer be required, since the next job is likely to have different output requirements. The next job should clear all previous job settings by performing a reset. This allows a job to start with the default settings as a known base set, and vary only those settings that are needed. Starting with the default environment at the beginning of each print job eliminates the need to set every feature each time a job is run. Note The print environment features presented in this chapter are for a variety of HP LaserJet printers. Not all of the features are applicable to every printer. To identify variations and default settings for specific printers, refer to Chapter 3 of the PCL 5 Comparison Guide. EN Introduction 3-1 Factory Default Environment A factory default is a feature setting programmed into the printer at the factory. The group of all of the printer's feature settings set to their factory settings is referred to as the Factory Default Environment. These features are described in this manual. Since the HP-GL/2 features are used for HP-GL/2 operation only, the print environment features are separated, for convenience, into two lists or contexts: PCL and HP-GL/2. Table 3-1 lists typical PCL print environment features, and Table 3-2 lists typical HP-GL/2 print environment features. Note he factory default settings for the printer features are not shown here, since they differ depending on the printer model. To identify variations and default settings for specific printers, refer to Chapter 3 of the PCL 5 Comparison Guide.

Refer to the printer User's Manual for instructions on how to select these user defaults from the control panel. The PJL (Printer Job Language) "SET" command overrides the PCL user default environment for the duration of a PJL job. If PJL is not active, then the PCL user default environment has precedence. Refer to "PCL Commands" in Chapter 1 for more information. 1.
