PostScript Processing Speed Test, bitmap test

What is the PPST bitmap images test?

The bitmap image test is pretty simple; at the end of this file is a series of hex digits. When the test is first sent to the printer, all those digits are stored in RAM and later put on the page. There are three images in all, and all are low resolution images because of programming constraints and memory limitations. Before you ask, I can not make a higher resolution test without making the PPST file jump from about 200-300K to about 2 to 3Megs!!! Also, keep in mind that the way the test is designed (because of it's low resolution) lets you see how your device deals with low resolution images. Of the three pictures on the page, two are in color (256 colors) and the top one is B&W. The test simply puts those pictures on the page and prints the page. Keep in mind that PPST doesn't print the bitmap as it receives it which is the case with most bitmap printing, so you get the "real" bitmap image speed, not something dependant on the data reception time!
