Hi Guix, I was setting up a new printer but when I wanted to print in emacs it gave me this message: Send selected text to default printer? (y or n) y Spooling with options -P HP_Officejet_J4500-series -o sides=two-sided-long-edge -o number-up=2... condition-case: Spooling with options -P HP_Officejet_J4500-series -o sides=two-sided-long-edge -o number-up=2...done: /home/gfp/.guix-profile/bin/lpr: Error - The printer or class does not exist. I set up the new printer in cups and I also edided the init.el file in emacs to change the printer name. So I don't know at the moment what I can do. -- Kind regards Gottfried
