[CUPS] review jobs before printing
I'm on my way installing a linux cups server for network printing. What I want to do is to block all jobs from the server till the admin authorizes them (exactly, I want to review what is going to be printed before it is).
How can I do that with cups ? I tried changing the Require line as below
# Only the owner or an administrator can cancel or authenticate a job...
<Limit Cancel-Job CUPS-Authenticate-Job>
# was Require user @OWNER @SYSTEM
Require user @SYSTEM
but it seems CUPS sends the jobs to the printer anyway... Is there something else to change ?
Thanks for your help.
