* Edit cupsd.conf. Please insert the following lines at the end of the file if your currenct version of the file doesn’t have these values.

#
# JobRetryInterval in Sekunden
#
# The JobRetryInterval directive specifies the number of seconds
# to wait before retrying a job. This is typically used for fax queues
# but can also be used with normal print queues whose error policy
# is retry-job.
# The default is 30 seconds.

JobRetryInterval 15

#
# JobRetryLimit
#
# The JobRetryLimit directive specifies the maximum number of times
# the scheduler will try to print a job. This is typically used for
# fax queues but can also be used with normal print queues
# whose error policy is retry-job. The default is 5 times.
#
# 40 reicht aus, um Drucker in
# 10 min einzuschalten , damit die Jobs noch gedruckt werden

JobRetryLimit 120

* Edit printers.conf. Change the line ErrorPolicy to ErrorPolicy retry-job

# possible values for ErrorPoliy:
# abort-job – Abort the job and proceed with the next job in the queue
# retry-current-job – Retry the current job immediately
# retry-job – Retry the job after waiting for N seconds; the cupsd.conf JobRetryInterval directive controls the value of N
# stop-printer – Stop the printer and keep the job for future printing; this is the default value

ErrorPolicy retry-job
