Printer errors–Drivers
I had a customer who was getting printer errors using our USB Printer Adapter. He had installed the manufacturer drivers (HP I believe) But every time he would restart the computer or reconnect his printer, it would install the printer again so he would have extra copies of the same printer in his printer and faxes folder. The extra copies were using Microsoft drivers–and had (ms) with the name of the printer.
He tried to delete the extra copies of the printer, but every time it would reinstall. Eventually he uninstalled all of the copies of the printer, then reconnected the printer. Like usual the printer reinstalled with a Microsoft driver. He opened the printer properties, then through the advanced tab, updated the driver on that copy. It loaded the manufacturer driver and stopped reinstalling extra copies.
