I have an Epson Sylus Color Pro 500. I can print from DOS mode. I can print from safe mode. I can NOT print from a normal boot. I have uninstalled and re-installed to no effect. Device manager does not show any conflicts. This just started the other night when I changed BIOS on my old computer. Even when I restored the old BIOS the problem continued. It's now worse as I have a brand new motherboard and therefore the changed bios is no longer an issue. The problem, however, remains. It has my friends and I stumped and me totally annoyed at my inability to print in normal fashion.
