Windows 8.1 doesn't completely approve my printer

[Fisherman]

My Windows 8.1 (64) doesn't recognise my HP Designjet 111 as a printer - it is listed as undefined in Devices and printers. However when I check with regedit it is under USBPRINT not USB. What am I missing?

From the Devices Manager, uninstall the Printer driver. Restart your computer, connect to the Inernet and then plugin your Printer. Scan for Hardware changes and let Windows install the driver for your printer.

If it does not help, run the built-in Hardware Troubleshooter and see if it helps.
