According to the documentation, a job is retried only JobRetryLimit times. I see no reference to zero being a special value meaning 'retry until maxint' or 'retry until end of days'. If a read scheduler/job.c (cups_1.3.8-1+lenny6) correctly, zero indeed does not have a special meaning.

Correct, you'll need to use a really big number right now - 2147483647 (INT_MAX) will effectively retry "forever" unless you set the JobRetryInterval to 0, in which case it'll retry as quickly as possible.

Sure, please file it at:

We can put it into CUPS 1.5.
