Any printer problems will soon be somebody else's problem. I'm quite happy to leave all printing problems behind me. Printers seem to be a never-ending source of problems... -- //Sorin

Namely: 1. Configure all printer to not accept jobs (or talk to) any machines except for your UNIX print server 2. On print server make sure to use protocols to talk to printers that do not time out and stop CUPS queue. E.g., jetdirect (port 9100) never will. 3. On print server set some restrictions so to fend off those who shouldn't print to your printers. Restricting in local firewall on print server machine access to print ports to local subnets of your Department is one of the measures. I am setting stuff like above for at least a decade and a half and do not have to resolve printing problems. Originally I have to configure printing on users machines (Linux workstations get that from kickstart file upon build), and sometimes I have to explain users that they can not print from home: if you can not pick up your print job, you shouldn't be printing it. That said, I do have to mention: way back (almost two decades back) you couldn't configure access on some of HP printers... but sysadmin can always find workaround: I gave in printer configuration as gateway the IP of print server (which was on the same subnet) instead of real gateway of network, and that did it: printer was talking only to print server. When there is a will, there is a way. Thanks.

I wasn't trusted with the *nix farm yet then. Over the years I have tried at least once a year to get our Linux-computers to talk to our AD-connected Windows Servers, but haven't quite made it yet. I've also tried to get the AD-connected Windows-clients to talk to a Linux print server to no avail. Granted it's been awhile now since I tried. Maybe I'll give it another go. Both the Windows and Linux OS:es have developed quite a bit the last ten years... -- //Sorin
