Bug#1062554: cups-browsed is not detecting any network printers
Jonathan Kamens
Version: 1.28.17-3+b1
Severity: normal
Dear Maintainer,
cups-browsed on this laptop is not detecting either of the printers on
my home network.
I have another Debian laptop upstairs, on the same wifi network,
installed and configured pretty much exactly the same way as this
laptop, and it IS detecting printers on my home network.
I can't figure out why this laptop isn't detecting remote printers and
the other one is.
I tried rebooting, didn't help.
I compared cupsd.conf and cups-browsed.conf on the two laptops, and
the only difference is the DebugLogging line I uncommented on this
laptop while trying to figure out this issue.
I have been able to print from this printer before without this
trouble, so this is a new problem.

I also can't print to a printer I add explicitly to the system rather than relying on auto-discovered printers.
Basically printing through CUPS appears to be completely borked, at least for me, across two diffferent laptops running Debian testing.

It turns out things aren't working right on my second laptop either. It is correctly detecting network printers and making them visible to the OS as driverless printers, but I can't print to them. When I try, the print job gets paused and lpstat -t prints "No suitable destination host found by cups-browsed." This happens even after I reboot.

*sigh* Ignore everything I said about my second laptop. The cups-browsed problem I originally reported persists, but I believe everything else was a PEBKAC issue. Sorry.
