Sounds strange to me, that the screensaver did in fact stop the printing
job...

Not permitted sounds like you have to do that as root...

There is the command lpq to see what is in the queue and lprm to remove
a job from the print queue.

% lpq -PHP5L

-> prints the queue of printer with the name HP5L. In this queue you see
the different printing jobs with their job numbers. Then with

% lprm -PHP5L 500

-> you can kill job number 500 from the queue of printer with the name
HP5L.

If you are using RH9 you might have a tool to do this in a graphical
user interface ... not sure.

Kind regards.

Depending on the printer you can press a combination of button on the
printer.
