A way to delete finished jobs needed

What for?

- a teenager who doen't want his dad to see he printed playboy pics
- a dad who doesn't want his wife to see he printed a gift coupon for her birthday.
- ...

Maybe something like that. I know, I know, seperated users, etc. but I think that feature is somewhat elementary and would be easy to implement. So why not? Who knows why somebody want to delete the printers history

"Easy to implement"? Which IPP operation would you use for this? (Note that it has to work for remote CUPS servers as well as local ones -- like everything else in system-config-printer.)

If you want job-level or printer-level security, use the LSPP patches with a correct configuration. If you don't want the CUPS server to preserve job history, put 'PreserveJobHistory No' in /etc/cups/cupsd.conf.

It is very far from clear that adding any hacky cludge to "remove" preserved job history would add anything in the way of security, and it would definitely add other problems.

I agree that adding a feature to s-c-p to hide old print jobs would be a cludge (AFAIU local jobs could be deleted from the ,log, while remote jobs would need to be hidden). Many ubuntu applications have history of some sort; perhaps what we need is a central panel to handle privacy concerns (needs a blueprint).

FWIW, there is the IPP_PURGE_JOBS request; however, (a) by default that requires admin, and (b) it can only operate on all jobs at once.

Now this is elementary - if something is WRITING the data to a location , then something can ERASE data from that location.

Having any sort of history that is unremovable (even with "under the hood tinkering" could preclude Ubuntu from ever being used in a secure or restricted environment. I consider this a security flaw!

This MAY have something to do with the CUPS Printing system interface:

http://127.0.0.1:631/

as I can see teh jobs there, too, but can not clear or cancel them.

I agree that it would be nice to have a gui option to selectively delete printer history.

But I've tested and if you go to System > Administration > Printing > Server > Settings > Advanced you can change the option from "Preserve job history but not files" to "Do not preserve job history".

Of course that doesn't clear the previous history, but it prevents the recording of any new history.

IMHO that should be the default anyway!

Oops should have mentioned that I tested in Jaunty!

Thanks Eric, now how to clear the remaining 46 job data - Like I said, this is a SECURITY issue - will someone ensure this is flagged as such?

Tim Waugh, curious as to what this is? I thought Ubuntu was Debian based or is CUPS a Fedora based application, or what? Thanks.

The system-config-printer application is a Fedora project, written for Fedora and Red Hat Enterprise Linux, and adopted by many other Linux distributions.

This has been fixed according to the upstream bug report and in Ubuntu 10.10 (maverick) I'm able to delete completed jobs.
So closing this bug report.
