TurboPrint & PrintFab

This is the end of the output of /var/log/turboprint/print.log when trying to print a test page: Colormatch file=PGI5CLI8; Curves=600dpi_quick_plain_ip4200; Table=plain_paper Report at end of pdrive_class::begin_page Total memory usage=1212937 PREVIEW y_offset=70 org_height=6600 src_scanline=70 prev...

I just noticed that /sbin/yast2 is hanging when I go to the hardware | printer configuration screen. This is an AMD x86_64 system.

Please respond with any suggestions: tail -f /var/log/cups/error_log D [12/May/2011:11:13:09 -0400] [Job 66] Wrote 1 pages...

sudo /usr/sbin/cupsenable tp0 changes 'Stopped' to 'Idle' in the TP monitor, but printing a test page fails with the following log output. (Also, clicking on 'Accept Jobs' still locks up the TP monitor. tail -f /var/log/cups/error_log D [12/May/2011:11:13:09 -0400] [Job 66] Wrote 1 pages... D [12/Ma...

OK. I've done that. Now, when I bring up the monitor and try to print a test page, it shows 'pending' and 'no active jobs'.
tp0 is shown as stopped. Hitting Start/Stop job toggles from 'pending' to 'held'.
If I click on 'accept jobs', the monitor locks up.

I found the following in /var/lib/cups/error_log: E [28/Apr/2011:15:55:20 -0400] [Job 44] Stopping job because the sheduler could not execute the backend. E [28/Apr/2011:15:56:24 -0400] [Job 43] Stopping unresponsive job! E [28/Apr/2011:15:56:44 -0400] Unable to execute /usr/lib/cups/backend/smb: in...

I have tried reinstalling TurboPrint 2.2. The problem persisted.

Jobs show up in the monitor as 'stopped'. They can't be restarted and they never reach the printer. The monitor does not display any error messages. The printer is attached to a Windows box and is accessed by TurboPrint as a cifs share.

TurboPrint 2.2 has stopped working on OpenSuse 11.4 with my Pixma MP830, possibly with the update from 11.3 to 11.4. Can you suggest a method for debugging?
