Printer requires an Owner Name

[Al]

My work has switched to Fuji Xerox printers, which up to today I've been able to print to simply by sending a PostScript file to their IP addresses. But as of today printing requires a login. Here are the (Windows) instructions:

"Start>Settings>Printers and Faxes>R-Click on the printer>Properties>Configuration>Accounting>Change the dropdown box “Use Login Name” to “Enter owner name”>Type in your staff ID number in the User ID box e.g. “e*******”>OK>Apply"

All very nice, I'm sure - but how do I apply this to CUPS? Where can I find an owner name in CUPS?

Thanks very much,
Al
