Raster Image Graphics
These 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.
