The AppleWriter is a write black printer while I expect from the problem that the Dataproducts is write white. Each printer will have its internal pixel generator for text tuned for its print engine -- hence text looks correct on both, but for bit maps you notice the difference. I don't know if anyone has a simple solution for printing bitmap images --- the software that generated the bitmap image may have parameters that can be changed to produce write white images. This is what has to be done when generating pixel maps with METAFONT for TeX fonts -- you need one set of pixel maps for write white and one for write black ;-( david shepherd INMOS ltd
