 cups stops printing - says processing
I have been having this problem since the new install of Fedora 10. Previously used fedora 4 with no problems.
HP 1320 laserjet attached to the parallel port printing directly from IBM UniVerse installed on the fedora box. Everything works great but several times a day, printing the same things all day (occasional customer orders) the printer stops working. Cups job status says processing, and the last few lines of the cups error log says "Saving Subscriptions.conf" about 5-6 times. No errors in the log at all. Here is error log from print job that froze. This job was 3 pages and it printed two of them and then froze.

Like I said, Cups says "processing". when I look up the job. My only way out is to delete the job and restart cups, then I am able to print until it happens again. I have tried different print drivers, including a generic text only driver. And I have also used hp-setup to install the printer. The same thing happens every time with every different set up.
Any help would be appreciated....

Mike
