TWAIN is an industry standard that allows scanning directly into any TWAIN-compliant software. It eliminates most compatibility problems associated with software and input devices supplied by different vendors. You can access the TWAIN dialog box from within most image editing software such as the application software bundled with the scanner (e.g., Photoshop®). 4 To Acquire the TWAIN Dialog Box You can acquire the TWAIN dialog box from within any TWAIN-compliant software (i.e., Photo ExpressTM). To acquire the TWAIN dialog box, using Photo Express as an example, the steps are: 1. Launch Windows®. 2. Launch Photo ExpressTM (TWAIN-compliant program). 3. Under the File menu, open the Acquire command and choose Scanner. The Select Data Source dialog box appears. 4. Choose your scanner model from the list. 5. Click the Acquire button.
