Thank you for your report, David.

Thank you for responding.


Please post the entry for the printer in /etc/cups/printers.conf.

$ sudo cat /etc/cups/printers.conf
# Printer configuration file for CUPS v1.5.3

To test, set up a print queue with

   lpadmin -p test -v ipp://192.168.7.19 -E

$ sudo lpadmin -p test -v ipp://192.168.7.19 -E


and print to it with

   lp -d <file>

$ lp -d Data/dpchrist/Downloads/f/fsf/licenses/gpl-2.txt
WARNING: gnome-keyring:: couldn't connect to: /home/dpchrist/.cache/keyring-oIagOw/pkcs11: No such file or directory
lp: The printer or class does not exist.


The printer doesn't exist, so the command

   lpstat

$ lpstat
WARNING: gnome-keyring:: couldn't connect to: /home/dpchrist/.cache/keyring-oIagOw/pkcs11: No such file or directory


as a user should show the job as being queued.

   cancel -a

$ sudo cancel -a


as root should remove the job from the queue. This is shown by

   lpstat

$ lpstat
WARNING: gnome-keyring:: couldn't connect to: /home/dpchrist/.cache/keyring-oIagOw/pkcs11: No such file or directory



   ls -l /var/spool/cups

$ sudo ls -l /var/spool/cups
total 4
drwxrwx--T 2 root lp 4096 Jan 11 12:08 tmp


and, with debug logging set, the error log.

Where is the error log?


David
