Comment 19 for bug 692568

This issue occurred on a Debian Jessie system today with the following series of errors in the CUPS log while attempting to send print jobs:

E [20/Nov/2015:10:22:41 -0800] [Job 1828] Unable to send data to printer.
E [20/Nov/2015:10:27:46 -0800] [Job 1828] Stopping unresponsive job.
E [20/Nov/2015:10:47:07 -0800] Missing printer-uri, job-uri, or ppd-name attribute
E [20/Nov/2015:10:47:07 -0800] [Client 17] Returning IPP client-error-bad-request for windows-ext (no URI) from 10.0.1.15
E [20/Nov/2015:10:50:07 -0800] Unable to communicate with avahi-daemon: An unexpected D-Bus error occured
W [20/Nov/2015:11:16:25 -0800] CreateProfile failed: org.freedesktop.ColorManager.AlreadyExists:profile id 'HP_LaserJet_1200-Gray..' already exists

To Till Kamppeter above: for me the error was resolved by going to Administration -> Manage Printers -> HP_LaserJet_1200 -> In the dropdown that has "Maintenance" selected by default, select "Resume Printer".

A UI problem is that "Resume Printer" should be a button, not an entry in a menu that otherwise changes screens. Bigger UI problem of course is lack of any indication that a printer is paused outside the "Resume" option appearing hidden in a drop-down menu.
