Hi,

I knew better than to take the machine down for maintenance. I only replaced a tape drive and cd burner and installed a few minor Fedora updates.

The setup:

Linux monolith 2.6.22.14-72.fc6 #1 SMP Wed Nov 21 14:10:25 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

CUPS 1.2.12

I have 11 printers setup--a mixture of laser printers connected into the network and parallel dot matrix printers connected via d-link printservers.

Since the reboot, each of the printers has stopped in a seeming random fashion. All it takes is for me to start the printer again from the web-based CUPS administration printers page. The problems are not limited to printers on the d-links.

I saw references to the problem and changed printers.conf / ErrorPolicy from "stop-printer" to "retry-job". That seems to have changed the symptoms from stopping the printer to holding the job. Now I have to go into "jobs" and release them.

Here is the printers.conf configuration for one printer:

<Printer dfx5kp-M>
Info Line Printer
Location Front Office
DeviceURI lpd://192.168.40.50/PS-804A7B-P1
State Idle
StateTime 1233242227
Accepting Yes

JobSheets none none
QuotaPeriod 0
PageLimit 0
KLimit 0
OpPolicy default
ErrorPolicy retry-job

and error_log for an offending job:

Note: I received the message that the host did not respond after 300 seconds only seven seconds after it was queued.

Gladly taking suggestions.

Thanks,
