I have my printer at school that is driving me nuts. It's an HP Laserjet P1505n that has been installed and functioning properly for the last three years or so. The janitors came along when they were waxing the floors and disconnected everything. Usually, that's not a big deal, but for some reason this time, when I connected it all back up, the computer won't recognize the device anymore. It will give a "USB device not recognized" message. All of the connections are secure. I know that the USB ports on the machine are working because I swapped the mouse around and it worked.
I tried uninstalling the printer and reinstalling with the install CD. No luck. I then grabbed another printer out of storage (an HP Laserjet P2015) and tried installing it with the install CD. No luck again. When I try to add a printer and have the computer search for the printer through plug and play, it can't find anything. When I tried to manually install, it ends up giving me the message "Unable to install printer. The print processor does not exist."
I searched for that message and found a suggestion to copy the print processor files from a different machine and install them on the nonworking machine. Tried that, didn't work.
Any thoughts on what is going on here? I'm going back to school tomorrow to fight with it some more as I need my printer in the classroom. Thanks!
