Comment 2 for bug 254750

Please, can you attach the cupsys log: this is a file where CUPSYS writes information about what it is doing. Almost all printing problems can be diagnosed from the error log, so it is the first place to look to start solving problems. To be useful, you must change the logging level:

   1.Select "System" -> "Administration" -> "Printing" in the main menu of your desktop. The printer setup tool system-config-printer will open. Select "Server Settings" in the list on the left. Then check the check box "Save debugging information for troubleshooting" and click "Apply".
   2. In /etc/cups/cupsd.conf, find the line "LogLevel ..."; change it to" LogLevel debug"; save.
   3. 'sudo /etc/init.d/cupsys restart'
   4. Try to print something.
   5. Add /var/log/cups/error_log as an attachment to the bug report.
