I have a client with a P4 celeron 1.7 Ghz system running XP HOME. All was fine with her 560C HP printer until I added service pack 1 and current updates to her computer last spring. Every time the computer is restarted it finds new hardware, and does not like the printer driver. I have updated the printer dirver with the same results.
She has since purchase a new HP printer, but every time she boots, it tries to re-install, does not like the driver. Once past this pint the printer works just fine.
