I am an absolute beginner with Ubuntu and I appear to have a long queue of documents in my H.P. 840C printer.

  1. The question was how to kill all jobs. The simple way to kill all jobs:

    lprm -

    The complicated linux old-school way is below:

    Command line:

    lpstat -o

    to view outstanding print jobs.

    cancel -a {printer}

    to cancel ALL jobs or ...

    cancel {printerjobid}

    to cancel 1 job.

    man page cancel

  2. Either

    1. Use the printer dialog: type "Printers" in the dash and navigate to the printer
    2. Use the CUPS web interface: point your browser at http://localhost:631/jobs/ and proceed from there
    3. Use the command line interface: use lpq to see jobs, lprm to remove. Refer to man lprm for more information.

  3. Use 

    lpstat -W completed -o

    to view list of completed jobs.
    Use

    lpstat -o

    to view list of not-completed jobs.

    And to delete job list,just use this command:

    cancel -a -x

    This will cancel all pending jobs, as well as deleting them.

  4. Well, answers given here didn't work for me so here's what I did -

    ps aux | grep printer
kill {printer job}

  5. I tried using lpstat and lprm but was unable to figure out basic things like the job number and stuff. Instead, I used the command:

    lpq

    This produced:

    zac@computer:~$ lpq
lpq: Error - no default destination available.

    A quick Internet search and then I tried:

    zac@computer:~$ lpq -a
Rank    Owner   Job     File(s)                     Total Size
1st     zac     85      TorahNT.odt                 59392 bytes

    FINALLY I find the all important Job number: 85!

    NOW I run lprm:

    zac@computer:~$ lprm 85
zac@computer:~$

    And to confirm I did this:

    zac@computer:~$ lpq -a
no entries
zac@computer:~$

    Finally, the printer queue is empty.
