Setting request-user on IPP printer in CUPS

  • 772

I need to send a request to CUPS server with the specific request-user parameter - remote_user instead of local_user. How should I set the local CUPS server?

  1. According to the CUPS release notes, support for specifying a different username was added in CUPS 1.6b1:

    • CUPS now supports a User directive in client.conf and the CUPS_USER environment variable for overriding the default username (STR #3114)

    The Ubuntu bug report below (I can't make it a link due to ServerFault limits) is another place to look for information and workarounds for pre-CUPS 1.6b1, although the workarounds are not very practical.

  2. If you print using this command:

    lp -d yourprintername -U yourusername /path/to/file

    you'll find requesting-user-name="yourusername" in CUPS' error_log file (but your cupsd.conf needs to be edited to use LogLevel debug for that message to show up).

    If you want to force a default option for all users, run this command as root:

    lpoptions -d yourprintername -o requesting-user-name=someusername

    [Note: some versions of CUPS seem to mix up 'job-originating-user-name' and 'requesting-user-name'. So you know if my suggestion doesn't work for you...]
