Printing ID on Workgroups

This is my first post so hello every body..

I have a Workgroup of 8 computers and a printer attached to one so all the other computers print through this. Can anyone tell me how to show the user account in the print queue? I have tried to make two user accounts one on the server and the other on the client but it still shows up a guest account. Both PC run Windows XP Pro

Thanks to any one who reply.
