At intervals I get complaints that one of the printers isn’t responding from a given machine. On investigation via the CUPS frontend the error is:
Restarting the printer from there works, but it is slightly irritating.
This has happened several times in the last couple of days on one particular (aging) machine, which prompted me to seek a better solution. I found this entry which explains at the bottom how to change the CUPS setup appropriately. Edit
/etc/cups/printers.conf and change the
ErrorPolicy for each printer from
retry-job. So far this seems to be working fine and I shall be rolling it out across the network.
