A Template on every computer Account and that has the Account Holders Name in it. But the problem with that is that it requires every application that can be printed from to have it's own Template and then for every User Account.
Without knowing what is really required by the Complaining Requirements it's very hard to say any more than that.
But just remember that you can print from Notepad, Word, Access, Excel the screen if necessary and if all of these need to have the Account Holders Name included on the Printed Page it gets a bit more difficult.
There are also Programs like Photo Editing that can print photos or Graphics Programs like Corel Draw that you can print from so you need to look at a Hardware solution if any of these are in use.
Really without knowing what is involved and the Network Configuration it's very hard to offer anything else.
