USB printer don’t print after reboot

Hi.
I’ve tried 2 hours to make it work but here is what’s happening.

I shared my USB
printer on XP home and I want to print from a W2K Pro.(all OS are up to date including Windows Update and SP’s). I can install
the printer on the W2K station and print as long as I wish until I reboot the XP PC. I have to re-install the printer on W2K each time I reboot. What can be wrong?

Thank You.
