Printer needs logging in - HOW?

[Matt Keller]

Hi

I'd like to use CUPS together with a professional Printer here (Xerox 
4110) which needs users to login because it does some internal accounting.

Xerox delivers drivers for Windows and Mac OSX - which uses CUPS as far 
as i know.
If i print from Mac OSX using the print dialog i get an entry called 
'Job Accounting' where i can enter a username and password.

Unfortunately I didn't find a way to provide those using command line 
options....?

Anyone got an idea how I could do this??

Thanks

Matt
