Printing to a Windows print server on a domain

Question

I work at a computer lab at my school and for a long while I don't think anyone has really researched this topic well enough.
We charge for print jobs based on username; whoever logs in get chraged for the prints they do. For windows machines this works perfectly fine, but for mac computers, if we set them up, they print directly to the printer and completely bypass the server, so for a long while our solution has been not letting the macs print. But now with Macs being more appealing for previous windows users people are getting more and more Macs. So my question is how can I set up a mac to print to our server, which is on a domain, and have it log who prints it by username?
I have searched around already and closest I'v come is on mac os x hints. Using advanced setup using the line smb://username:password@workgroup/computer/printer

But the problem is that it is for a workgroup not for a domain, which is what we have. So if there is a way we could do this it would really make a ton of people here happy.

Answer 1

It may be meant to work on both a workgroup and domain but when I set it up this way it always gives an error reguarding the fact that it cant find the workgroup that was specified. I can try again and give the exact error I get but I've tried all different ways I could think of.
I'm not sure if this would have any effect on it but the passwords used always have a special character in them like the period or comma and such.
Another thing is Would the software used to manage the printers on the server have any effect on how a mac can communicate with it? Or would the server just take any printjob its given and channel it to the right place?
