6.2 Specifying Graphics-Compression Data
Some printers support the ability to receive raster-graphic data in a
compressed format, which typically results in increased performance. The
increased performance is due to the reduced amount of data that needs to be
sent to the printer to print bitmaps. If your printer supports compression
of graphics data (that is, bitmaps) using run-length encoding (RLE) or Tag
Information File Format (TIFF) version 4.0, you should specify the related
data and commands in the Compression Modes dialog box. This dialog box
contains controls which identify the compression scheme, specify the Begin
Compression command, and specify the End Compression command. The Universal
Printer Driver version 1.0 only supports TIFF 4.0 compression. The
following illustration shows the compression dialog box:
bitmap: gicmprss
The Diconix 150 Plus printer does not support data compression; the HP
LaserJet IIP printer supports both run-length encoding and TIFF. The
LaserJet examples are based on the dialog box that contains commands for
TIFF encoding.
