My old computer had only 40MB memory and a 4 gig hard drive total, and Poser ran beautifully. I never had a crash and my renders went just fine. So I would have to assume that maybe you have a corrupt file somewhere. My new computer is an HP and I've always had an HP printer and it never conflicted with any of my programs, including Poser. I've never heard of this happening. I still use Poser with no problems at all. Have you tried uninstalling Poser and reinstalling it? Maybe something has gone astray. I hope you get it worked out.
