Description of problem:
I have a couple of examples of Epson USB printers (880 and C46) where this is true. When the printer becomes unavailable becuase it is, say, out of ink, cups puts the queue off-line.
When the ink cartridge has been replaced, and the printer is now available, cups fails to notice, and leaves the printer queue off-line.
This means that users (some of whom are not used to logging in as root) have to re-enable the printer queue using the KDE control centre (or whatever).
This seems a wrong design decision. I think the printer queue should be re-enabled automatically when the printer becomes available again.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Printer runs out of ink.
2. Queue goes off-line
3. Change ink.
4. Printer now available again.
5. No printing happens.
6. Re-start printer in KDE control centre (as root)
7. Printing happens happily once more.
The problem is that users cannot get the queue to re-start, even by re-booting
the machine. And we don't want naive users to get frustrated with Fedora do we? :)
Well, another way of looking at this problem is that there is no obvious way for
someone to re-enable the queue once it has been automatically set offline.
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.
FWIW, CUPS-1.2 now allows a policy to be set to avoid setting the printer
off-line; and the FC6 config tool will allow setting printer's on-line again.
