I have an HP Laserjet 1012 attached to the network with an HP print server. I installed the printer on the Windows 2003 server using the driver on the CD that came with it and initially it printed fine. It didn't take long to start getting the error "unsupported personality: PCL" whenever a print job was sent to it. I did some checking and read that this printer requires a host based driver, so I downloaded the Server 2003 Host based Driver from HP's web site. I attempted to add this driver and get an error that says the action cannot be completed and the driver is not installed. I tried using the setup program on the CD and it fails with errors too. Now the print spooler subsytem gives errors and shuts down. I can manually start it, but it fails immediately and all the printers on this server are down. Any ideas?
