Printer paused, "/usr/lib/cups/backend/dnssd failed"
Tyler Smith
I irregularly have a problem when trying to print to a network printer
from my Debian Testing laptop.
Initially, after setting the printer up via the CUPS web interface,
everything worked fine. Now, sometimes, sending a job to the printer
results in the printer reporting (via localhost:631/printers) that its
state is "Paused", and "/usr/lib/cups/backend/dnssd failed".
I don't yet know why it works sometimes and not others. I've tried
restarting CUPS (/etc/init.d/cups restart), but that doesn't seem to
help. I tried google but found either general discussions that didn't
address my specific problem, or detailed discussions I didn't
understand. I think I've got the printer itself properly configured, as
it does work occasionally, and I had no problems for the first six
months or more after installing it.
What should I try next?
Thanks for any suggestions,
Tyler

By Googling around, it seems to be a problem with "avahi", so you can try
restarting "avahi-daemon" service.

Sorry, I should have mentioned I also found that with Google, and tried
restarting avahi-daemon without success.
Thanks,

How did you setup the printer?
Try by using a "socket://" or "ipp://" URI and the IP address of the
printer/machine instead using its name to avoid "dnssd" service comes
into play.

Thanks. It worked fine for a couple of weeks, then stopped again. After
that I reconfigured the printer using socket://<ip>:9100 (for an hp
printer) and it seems to work again without requiring a reboot or mystic
incantations.
Cheers,
