Maintain correct user name when print jobs are redirected on CUPS
When print jobs on CUPS are redirected to a second print queueA print queue displays information about documents that are waiting to be printed, such as the printing status, document owner, and number of pages to print. You can use the print queue to view, pause, resume, restart, and cancel print jobs. the job seems to come from a user account called
lp. Note that the job is still correctly tracked against the user and the approriate accounts are charged as needed. However, some users can be confused when their jobs appear to be printed by another user at the device.
Administrators can edit the file ~/providers/print/linux-x64/print-provider.conf and uncomment the
RedirectCommand entry. This forces PaperCut NG/MF to pass the user's name to the CUPS subsystem on redirection. This is not the default behaviour as it can cause authentication problems, depending on how your network printer queues are configured, and you should verifty that users can still print after making this change.
