Bug#931560: cups-backend-bjnp: refuses to print with "out of paper" error
Package: cups-backend-bjnp
Version: 2.0.1-1
Severity: important
Tags: upstream
Dear Maintainer,
Printer: Canon PIXMA MG6150
Backend: bjnp
Upgraded to Debian buster, cups now refuses to print with error
"Network host '...' is out of paper, will retry in 30 seconds..."
Tried restarting the printer, restarting cups, manually removing
'Reason' lines from /etc/cups/printers.conf (while cups is off),
nothing solved the issue.
I took a look at upstream changelog and noticed this for 2.0:
> Ink level reporting is added as well as improved error handling.
I suspected that there could be a regression, so I downgraded the
package (and only this package) to the version in stretch (1.2-2)
and the problem went away instantly. I didn't even need to restart
cups: the new bjnp backend started printing in the next automatic
retry. Tried upgrading again and problem returned; downgraded and
problem disappeared.
Note that I have a few ink cartdriges that are nearly running out,
but not low enough that the printer refuses to print. It could be
possible that the new ink level reporting code is misinterpreting
this condition as an "out of paper" condition. Unfortunately I
don't have new cartdriges at hand to test this hypothesis.
