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

As far as we are aware this command on Wheezy works. There have been no
reports saying otherwise.

To test, set up a print queue with

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

and print to it with

  lp -d <file>

The printer doesn't exist, so the command

  lpstat

as a user should show the job as being queued.

  cancel -a

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

  lpstat

  ls -l /var/spool/cups

and, with debug logging set, the error log.

Regards,

Brian.
