How can I change/map/force originating-user-name attibute for a printer?

Does this printer use any feature like "locked printing" or "secure printing" or similar, where only authenticated/known users can retrieve their jobs after typing in a PIN into the printer console?

Are you sure you are sending the jobfile in a format which is not understood by the printer?

Is this a PostScript printer?

Which PPD do you use on the CUPS side for it? What is the complete line starting with "*cupsFilter" in this PPD?

If you are using already the Windows "username:password" encoded in the smb-URL (which in general is a very unsecure thing to do, and only an "emergency crutch" to use for lack of better means), then it means that you can not do anything else here.

If you are part of an Active Directory, you may want to look at the package "samba-krb-printing" (at least that is  what it is called on openSUSE 10.2). It was written by the Jeremy Allison from the Samba Team as wrapper for the  current "smbspool" utility (the one you are using right now) that uses Kerberos. Have a look:
