Hi
I use an "HP deskjet 990 cxi" with my atari software in gemulator atari emulator on a PC - it works fine. I haven't tested it extensively with a real Atari but it worked fine with ist word plus. You may need to experiment with various HP dekjet drivers in different atari apps to find the one that works best. Sometimes HP deskjet 500 is good, or HP deskjet 850C may be better depending on the app your using.
