I try to install my printer using the following command:
As you might expect my printer has the IP 10.2.1.99. It is a HP Color LaserJet 2700n.
Everything works well until the very last step when I have chosen the PPD file and clicked Add Printer. I then get prompted with a box where I can write Username and Password, and the text:
You do not have permission to add a printer
I've tried entering credentials to all accounts I can think of that exists in our office, but it does not seem to work.
If I press cancel when prompted, I get this text in the console:
Printer queue setup failed. Could not connect to CUPS Server. Is user added to "lpadmin" group(s)
What permission is it that I need?
