CUPS print server control
I have a CUPS print server (RH Ent3, soon to be RH Ent4) setup which accepts jobs from multi-platform systems on a specific subnet. What I'd like to ask if if anyone knows of any software that will allow me to have more control over what is printed. In short, I don't want to monitor each and every print job but I'm having PEBKAC issues where certain users print 20 pages of a document and it ends up printing 20 copies of the 20 pages. I'm sure the problem is due to the specific users using Apple OSX drivers to print to the Linux print server but I'd like a way to block print jobs that fit certain criteria dictated by me. Does anyone know of any CUPS front-end software that will give me more control than the default CUPS admin interface?
