[Message part 1 (text/plain, inline)]

Hi,

currently, the Guix guided installer does not set up printers and
scanners (see bug# 38064), making those not work after installation.

It would be good to extend the Guix installer to also install "cups" and
"sane-backends" services, just like it already does for networking services,
if applicable.  Long term, we could also do the actual configuration, but
right now even just the services below would already be a big improvement:

The relevant operating-system config snippets are:

  (services
    (append
      (list (service cups-service-type
             (cups-configuration
              (web-interface? #t)
              (extensions
               (list cups-filters escpr hplip-minimal))))
            (simple-service 'custom-udev-rules udev-service-type
                            (list sane-backends))
[...]

This bit above would have to be opt-in, but…

… this one could perhaps be enabled by default for “desktop”
installations, since, I believe, it doesn’t increase the disk space used
by the resulting system.

WDYT?

Thanks,

This could be sane-backends-minimal. I checked the udev-rules in both of
them and they're identical.

At the very least I think the udev rules should be added to the cups
service.

Hmm, does cups have anything to do with scanning? 

Long term, people will not print things anymore but will scan things
(until such time where that stops, too), so "cups" will be way less
important that "sane" in the long run--and, if optional, it can easily
be that a user has "sane" but not "cups" in the system.

I'd prefer to just add

  (simple-service 'custom-udev-rules udev-service-type
    (list sane-backends-minimal))  

unconditionally (if it doesn't increase the size anyway).

This does not match my experience.  Printing things at university for
free (up to a quota) is very popular with students.  Many prefer
reading on paper or making notes.  Paper is like a cheap extra screen.

Nonetheless, instead of making hplip a default, I would prefer having
a video on how to install and configure printing services among top
Web search results.  This sounds like much work, but I’m not sure how
much work it really is.  Installing services is really easy on Guix.

Regards,
Florian

In this context, students to not need to run the CUPS daemon on their
laptop though: they just need to fill out ~/.cups/client.conf so that it
talks to the right pool server, and then everything should “just work.”

The installer is now proposing to install the cups service.

Closing, thanks.
