Printing Error on client machine

[Perins]

Printers are installed through GPO on each network machine, we have 20 machines that are currently not applying this GPO. I have ran a GPO Results Wizard and all policies apply fine. Logged in locally and tried to manually install a printer and error of "Windows can't install as port unknown". I have attached a screenshot from the eventviewer on the server which is 2008 R2.
