HP software Vista 64 woes

In downsizing my business I moved my office to my home. My old HP2840MFC
needed a drum, and I was tired of it not being able to scan under Vista. I
bought a CM2320nf, and networked it to my 2 Vista 64 computers. I previously
had a 5590 scanner and a D7160 photo printer that would not allow HP
software to work correctly with Vista 64. Over the past year I have spent
hours working with HP support and one problem always remained. Some piece of
HP software would register a daily problem report. I was disappointed but
not surprised when I encountered the same problem with my latest printer.
