Virtual Win XP Mode stopped HP LJ Pro M1212nf MFP printing in Win 7 Pro: I am running Windows 7 Pro with Virtual Windows XP Mode. My printer is HP LaserJet Pro M1212nf MFP attached directly to a USB port of the computer. This printer was working fine in Windows 7, until I tried to attach the printer to the Virtual Windows XP Mode in order to load the printer driver in the Virtual Windows XP Mode. At that point, the printer disappeared from the list of USB devices on the toolbar at the top of the window of the Virtual Windows XP Mode. After installing the printer driver in the Virtual Windows XP Mode, the printer did not work in that mode and also no longer worked in Windows 7. In Windows 7 and in the Virtual Windows XP Mode, print files are sent to the print queue, but are never printed. In Windows 7, the print queue states that the printer is offline. In the Virtual Windows XP Mode, the printer can be toggled from "Print Offline" to "Print Online", but no print files are ever printed from the print queue. The printer acts as though it is no longer connected to the computer, even though it is still physically connected to the USB port of the computer. How can I get the printer to work again in Windows 7? (At this point, I am no longer interested in using the Virtual Windows XP Mode.)
I have tried a large number of things to find and fix the printer problem, but have had no success. Device Manager cannot see the printer even though it is physically connected via USB port (have tried different USB ports) to the computer. Restoring Win 7 and Virtual Win XP Mode to times before the problem does not fix the problem. How can I get the computer to see the printer, so that I can print again in Win 7?
