Hi Jean,

I installed paps with my System GNU Guix
and I copied

into my init.el file

How does now the program paps find my printer?
because when I wanted to print something it says
"kein voreingestelltes Ziel/No preset destination

What else do I have to do?
Do I have to install pags in emacs?
Do I have to add something in my init.el file to find the printer?

Sorry, but I am learning

thanks for help

Gottfried
