Choosing a print encoding method

Encoding methods determine how image data is sent to a printer. By default, the printer driver transfers binary information to printers, but you can choose to transfer image data using JPEG or ASCII encoding.

Note that some printers only accept binary and JPEG-encoded image data through their AppleTalk or Ethernet ports, not their parallel or serial ports. Check the documentation that came with your printer if you need more information.

To choose an encoding method:

1. Choose File > Print Preview.
2. Click Show More Options if it's not checked.
3. Select an option from the Encoding menu"

ASCII

encoding gives a two-byte value to each pixel of your image, which means that ASCII files are twice as large and require about twice as much time to print as binary files. ASCII files can be sent over a wide variety of network printing protocols, so select ASCII if binary or JPEG encoding is not supported your printer.

Binary

encoding gives a one-byte value to each pixel of your image. Binary encoded files are smaller than ASCII files and print more quickly. However, binary data can be misinterpreted by some network printing protocols, which may cause a printer to respond slowly.

JPEG

encoded files are smaller than binary files, so they require less time to print, but using JPEG encoding decreases the image quality. Only PostScript Level 2 (or higher) printers support JPEG encoding, so sending a JPEG-encoded file to a PostScript Level 1printer may result in PostScript language errors.
