printing stopped suddenly

[a]

                  Hi,

         the printing stopped suddenly in the last week. I had about 20 page or two printing works and suddenly the printer not started the new one at all.

         There are some error messages like:

         IPP report KDE - managing module:

Unable to open parallel port device file "/dev/lp0": Permission denied

         error_log.7.gz-file:

 Started backend /usr/lib/cups/backend/parallel (PID 6405) for job 172.
 PID 6405 (/usr/lib/cups/backend/parallel) stopped with status 1!
 Hint: Try setting the LogLevel to "debug" to find out more.

 PID 6404 (/usr/lib/cups/filter/foomatic-rip) stopped with status 9!
 Hint: Try setting the LogLevel to "debug" to find out more.
 [Job 172] Backend returned status 1 (failed)

         What helps for the problem?



         During the summer time it would be nice to able to print different kind of maps and combined texts.

         Regards,
