Reject Large Network Print Jobs

So I'm not a network admin, but do manage an ERP system on our network and am dealing with an issue a bit more in your realm.

Currently our ERP system has a bug that regularly results in absurdly large print jobs being sent to the server by operators. I am interested in rejecting these jobs completely to save paper, toner, and stress.

I am aware that Papercut allows you to discriminate via user, and because the ERP software runs on the server that the printers are on I would assume I can just set the rules to manage jobs that originate from the servers account but I am not sure.

I can also disable the network printing and do it locally, but the same issue will exist on the client as well. If there is an easier way to do this on on both Windows and Linux (raspbian Pi's) clients than on the server I'm all ears.

Thanks for your time
