RASTER IMAGE GRAPHICSThese commands utilize the raster area. Before sending data, set the presentation mode, the
resolution, the compression mode, the raster height and width, and start raster graphics. These
parameters are in effect until you overwrite them with a different command or there is a printer
reset. To ensure that the printed image appears in the expected area, set width and height
parameters.
RASTER COMPRESSION MODE
The Raster Compression Mode command determines how raster data is coded. It affects the
amount of code required to create an image, and the efficiency of image printing.
Syntax:
ESC*b#M
Parameters:
0 Uncoded (default)
1 Run-Length Encoded
2 Tagged Image File Format (TIFF) Byte
3Delta
5 Adaptive Compression
9 Replacement Delta Row
999 Zlib
1002 Group 4
1003 Group 3 one dimensional
1004 Group 3 two dimensional K=2
1005 Group 3 two dimensional K=4
1006 TIFF word (16 bit)
1007 TIFF double-word (32 bit)
1008 Adaptive Compression (includes TIFF word and TIFF double-
word)
Descriptions and examples of the different parameters appear on the
following pages. Each example draws the same square outline 64 bits
(8 bytes) wide by 64 scan lines long.
