Alright I actually made a little bit of progress myself. If i go to HKCU\Printers\Connections\,,server,PRINTER03 for a user that has the problem and change this to HKCU\Printers\Connections\,,SERVER,PRINTER03 then it works. This would be annoying to do for all users and not everyone is supposed to have this printer and the problem also applies to new users. Does anyone have any tips? Thank you in advance!
