Have tried several times reinstalling the printer software, Did a fresh clean install of everything including the OS. Spent over 3 hours with HP to solve the problem with no joy. It will not print from word, pdf (Direct or saved) or my documents unless I use the sipping tool to send these to my pictures, then it prints fine. I've tried the automated fixer thing and it says no problem. Some place I read this may be a missing C:\windows\system32\Drivers\usbprint.sys. . . I looked and do not see this folder.
I began having problems when I was updating the printer software.
vista home prem. plenty ram/disk space, all updates, antivirous good.
