In the latest Jessie, I need to add my Canon MG2100-series printer to my HP 6530b laptop.
I went to 'system settings,' 'print configuration,' 'add printer,' and a window says this:
There was an error during the CUPS operation: 'cups-authentication-canceled'
Then a new window shows, a column and a row, the left column says 'other' highlighted, and the right row says 'URI.'
Do I input a URI of /dev/usb/lp0 or something like that? That input and the 'forward' button doesn't highlight.
That's in KDE. In Gnome, the window reads a printer as a MG2100-series, but an installation window appears and disappears very quickly.
In KDE it says the user needs to be in the lp or lpadmin group. In Wheezey, I thought the user group could add groups to a user, but in my Jessie, I can only change my password in the user window.
What can I do to add the printer?
