Hello,
Thank you for the detailed explanations. I'm almost there:
- I modified the file /etc/config.scm according to the indications of
Tobias G-R, added (gnu packages cups) in "use-modules", then performed
"guix reconfigure /etc/config.scm" and after restarting, I was able to
access the web interface of cups (http://localhost:631/).
- I added my network printer, used the ppd file from openprinting.org,
and the printer is recognized.
- when I print the test page, the cups web interface says that the
connection with the printer is established, but the printing fails due
to the error: "Filter failed".
In attached document, my config.scm file to know if it contains an
error and which filters are installed.
Any idea?
Christophe
