Maykel,

  I have seen this exact error when something tries to use cups before cups is
started. I mistakenly added 'cups' to the old DAEMONS line in rc.conf (instead
of 'cupsd') and it produced this exact error (see old thread: "[arch-general]
cups not starting on boot after last 2 kernel updates? -- where to put it in the
DAEMONS line?") Since my latest install during Dec 2013, I have seen this error
again once when cups failed to start on reboot after kernel update. I don't know
why. Manually restarting cups solved the problem and cups has started
automatically every time since. It just looks to me like something tried to
probe or user cups before it was running. I just checked my install and I have
not seen the error in the past 30 days.

  If you show cups running and still can't print, then I would propose stopping
and starting cups manually as a test. I am still unclear whether it matter if
you start 'cups' or 'cupsd' the .service files are identical. At present I have
started and enabled 'cups' and not 'cupsd'.
