This chapter shows how to select PCL emulation and discusses PCL emulation commands, along with resident PCL emulation font and symbol set support. To determine which commands your printer supports, see Appendix A: PCL Support. Selecting PCL Emulation Using SmartSwitch When SmartSwitch is enabled for both printer languages on an interface (for example, Parallel, USB, Serial Option 1, or Network Option 1), the printer automatically switches to the printer language being sent by your software application. The printer is shipped with SmartSwitch enabled for both printer languages in all interfaces. The printer examines all print jobs and switches dynamically between PostScript emulation and PCL emulation. Using the Operator Panel or MarkVision Professional If SmartSwitch is set to Off for both printer languages, you can select PCL emulation from your printer operator panel or from MarkVisionTM Professional. Refer to your printer user documentation for information on changing menu settings. 2-2 PCL Using Your Software Application To select PCL emulation, use the Printer Job Language (PJL) Enter Language Command. See "ENTER LANGUAGE Command" on page 3-3 for more information. See "Printer Job Language" on page 3-1 for the syntax and use of PJL. Warning: When you change printer languages, you may lose some or all previously downloaded resources, unless Resource Save is set to On or the resources are stored in flash memory or on disk.

Then, other dimensions (C - I) are derived from A and B. 2-8 PCL Note: The explanation of the printable area assumes the Print Area menu item is set to Normal. For more information about Print Area, see page 2-8. Print Area Menu Item The printable area is the area on a sheet of paper within which a pel can be printed. Logical page is a conceptual entity that defines the area in which margins (top, bottom, left, right) may be set and the area in which the PCL cursor may be positioned. The physical page border is the actual physical boundaries of a page. The Print Area menu item is available from the printer operator panel or through MarkVision Professional. For some printers, Print Area supports three values: Normal, Whole Page, and Fit to Page. Refer to your printer user documentation for more information. Normal setting Whole Page setting Legend: PCL Logical Page Area Physical Page Border PCL Printable Area Only Portrait Orientation shown for all settings The Normal setting, which is the factory default, means the printable area includes the entire page except the narrow border around the edge of the page. This is the nonprintable area. The printer measures margin settings relative to the logical page. 2-9 PCL For a more detailed explanation of the Normal setting, see "Printable Areas" on page 2-2. The Whole Page setting only affects pages printed when using PCL emulation. If Whole Page is selected, the PCL language sets the logical page area equal to the physical page dimensions. Since the logical page dimensions and the physical page dimensions are the same, in theory, the cursor may be positioned anywhere on the page. However, the PCL language clips the image to the printable area. So, the Whole Page setting is useful for printing scanned images that extend from edge to edge of a page. Some printers offer the Fit to Page setting. When Fit to Page is selected, PCL emulation or PostScript emulation formats a page using a printable area equal to the physical page, which is from one edge of the page to the other edge of the page. If you use this setting, no clipping occurs. In Fit to Page, the PCL emulation logical page dimensions are equal to the physical page dimensions, as in the Whole Page setting. The printer holds this formatted image in memory, but when the page prints, the image is compressed a small amount in both horizontal and vertical directions, and then centered on the physical page for letter-size paper only. This process creates a small margin around the image. This artificial margin prevents printing from one edge to the other, since doing so could contaminate the printer and cause printing problems. The following illustrations show an image held in memory for printing from one edge to the other and how the image would actually print based on the Fit to Page setting. Notice that a small border appears at the edges of the printed page, and the image is slightly compressed. Physical Page Edge Formatted Image with Fit to Page Printed Image with Fit to Page 2-10 PCL Font and Symbol Set Support for the Lexmark C720, T520, T522, T620, T622, and W820 Your printer has 86 resident fonts in PCL emulation, including 84 scalable fonts and two bitmapped fonts. Several parameters are used to select a font from the data stream. These include symbol set, spacing, point or pitch, style, weight, and typeface number. For scalable fonts, you can vary the size of a font by specifying pitch or point size. For bitmapped fonts, you must choose the pitch or point size listed on the font sample pages. You can print the font sample pages from the printer operator panel or through MarkVision Professional. Refer to your printer user documentation for more information. A symbol set defines which characters are available for a font and the code point for each of these characters. Your printer supports 83 symbol sets. The tables beginning on page 2-16 show the symbol sets available for each font in PCL emulation. Not all fonts support all symbol sets. You can select a font as the PCL emulation default from the printer operator panel or through MarkVision Professional. Refer to your printer user documentation for more information. The fonts are divided into two major groups. The first 47 fonts (R0 to R46) shown on the font sample pages are the standard PCL emulation fonts. The 39 remaining fonts (R47 to R85) are called Type 1 fonts and were originally defined for PostScript emulation, but now also work in the PCL emulation. The fonts are further divided into font groups A, B, and C indicating which symbol sets are supported by each font. For a list of the 47 standard PCL emulation fonts, see Table 2-5 on page 2-12. For a list of the 39 Type 1 fonts, see Table 2-6 on page 2-14. Both tables list the forward and backward compatibility font selection commands and the font group (A, B, or C) for each font. For more information on forward and backward compatibility, see page 2-12. For more information on selecting symbol sets, see page 2-16. For compatibility purposes, you can disable Type 1 fonts with the Printer Job Language (PJL) LTYPE1FONTS command. The factory default for these fonts is Enabled. See LTYPE1FONTS on page 3-46 for more information. 2-11 PCL You can also select fonts using PJL commands. The selection parameter is the number portion from the font identifier shown on the font sample pages, such as 0 or 76 from font identifiers R0 or R76. Use the PJL values shown in the tables beginning on page 2-16 to select a symbol set. If a symbol set does not have a PJL value, use the symbol set ID to select the symbol set. A font selection can be either temporary or set as the default. Use the following PJL commands to select fonts: FONTSOURCE, FONTNUMBER, PITCH, PTSIZE, SYMSET, SET, DEFAULT. See Table 3-5: "Common Variables for PCL Emulation" on page 3-47 for more information about these commands. Forward and Backward Compatibility Modes for the Lexmark C720, T520,T522, T620, T622, and W820 Your PCL emulation has forward and backward compatibility modes. The forward compatibility mode is used to emulate the fonts in the Hewlett-Packard Company's LaserJet 4050. The backward compatibility mode is used for compatibility with the Hewlett-Packard Company's LaserJet 5 and the Lexmark family of printers. Standard PCL Emulation Fonts Table 2-5 on page 2-12 lists the font selection commands for forward and backward compatibility mode for each of the 47 standard PCL emulation fonts. Since the font selection commands for the forward and backward compatibility modes are identical, they are listed together in the table. Most fonts are assigned a font group indicating which symbol sets that font supports. 2-12 PCL To determine which symbol sets are supported by a particular font, find the font group (A, B, or C) for the font in Table 2-5, and then see Table 2-7 on page 2-16 for the symbol sets that belong to that group.

For scalable fonts, you can vary the size of a font by specifying pitch or point size. For bitmapped fonts, you must choose the pitch or point size listed on the font sample pages. You can print the font sample pages from the printer operator panel or through MarkVision Professional. Refer to your printer user documentation for more information. A symbol set defines which characters are available for a font and the code point for each of these characters. Your printer supports 19 symbol sets. The table beginning on 2-20 shows the symbol sets available for each font in PCL emulation. Not all fonts support all symbol sets. You can select a font as the PCL emulation default from the printer operator panel or through MarkVision Professional. Refer to your printer user documentation for more information. The Lexmark J110 default driver is a host based printing solution designed to produce optimal performance for printing. The data stream is optimized to reduce network load requirements. The driver can use all fonts installed on a Windows or Macintosh operating system. The following table lists the PCL fonts, and the available point sizes and pitches for each font: Table 2-10: Lexmark J110 Fonts Font Name Available Point Sizes Proportional Fonts CGTimes CGTimes Italic Univers Univers Italic 5, 6, 7, 8, 10, 12, 14 5, 6, 7, 8, 10, 12, 14 5, 6, 7, 8, 10, 12, 14 5, 6, 10, 12 Fixed-Width Fonts Courier Courier Italic Letter Gothic 6, 12, 24 6, 12, 14 6, 12, 24 5, 10, 16.67, 20 5, 10, 20 6, 12, 24 Available Pitches 2-21 PCL Table 2-10: Lexmark J110 Fonts Font Name Available Point Sizes Proportional Fonts Letter Gothic Letter Gothic Italic 4.75, 9.5, 19 6, 12, 24 16.67 6, 12, 24 Available Pitches For the preceding fonts, the following table gives the typeface, symbols set, and symbol set ID.

It also demonstrates how you can link commands to abbreviate them. Control Codes Control Codes are single-character instructions.

The ESC control code notifies the printer that the characters that follow are to be interpreted as part of a command and are not control codes or data to be printed. 2-23 PCL Command Structure Most PCL emulation commands have the following structure: ESC &a#C Spaces have been added to this example for readability. The command parameter variables are indicated by a number sign (#). Table 2-13: Description of Command Structure Element ESC Description Decimal 27 or hex 1B Parameterized character from American National Standard Code for Information Interchange (ASCII) table (range 33 to 47 decimal) Group character from ASCII table (range 96 to 126 decimal) that specifies a group type of control Decimal character string value within specified numeric ranges; may be preceded by a + or ­ sign and contain a decimal point Termination character from ASCII table (range 64 to 94 decimal) & a # C
