I too would expect it to be an HP printer. In Devices and Printers, remove the printer. Click on any other printer to get the ribbon, then choose Print Server Properties. Go to the Drivers tab and delete any drivers related to the problem printer. If you get errors that they are in use, you will need to stop your print spooler, clear out any jobs in the print queue (any files in C:\Windows\System32\Spool\PRINTERS), then restart the spooler. If you STILL get errors that the drivers are in use, you'll need to stop the print spooler then manually delete the drivers.
