Hi All,

This is my keeper file on the default printer.

Hope this helps someone else.

Exactly what purpose does the "server default" printer serve?
Is it even possible to send the CUPS server a print job with
no printer specified?    AAAAHHHH!!!!!!



CUPS: manually correct the default printer

Reference(s):
   https://en.opensuse.org/SDB:Print_Settings_with_CUPS
   https://github.com/OpenPrinting/cups/issues/818

CUPS Web UI (https://127.0.0.1:631) fails to update /etc/cups/lpoptions
to a new default printer.   Note that this is on purpose,  The Web UI's
default printer is the server's default.  Not the local (client)
computer's default.


The local computer's defaults are found in:
   user:
       ~/.cups/lpoptions

   global (if not user default):
       /etc/cups/lpoptions


Fix action:

First, list installed printers:
    $ lpstat -p
    printer Cups-PDF is idle.  ...
    printer HLL2300D ...
    printer HLL2300D_ManualTray ...

To set the system defualt:
    # vi /etc/cups/lpoptions
    Default Printer_Name_from_lpstat_above
    # systemctl restart cups

To set the user's default:
    $ lpoptions -d Printer_Name_from_lpstat_above

To double check:
    $ lpstat -d
    system default destination: Cups-PDF

Note: this is the local user default, not the system default.

Example files involved:
    System:
        # cat /etc/cups/lpoptions
        Default HLL2300D

    User:
        $ cat ~/.cups/lpoptions
        Default Cups-PDF
