There should be a way to see the job queue

You should have a 'Manage Print Jobs' main menu entry somewhere, although it might be hidden by default.

Yes, a 'View Jobs' button (perhaps under 'Tests and Maintenance'?) could be useful although it exposes a graphical interface for masquerading as another user when cancelling jobs.

I didn't find a "Manage Print Jobs" item anywhere on the system; and also I think that the main printer control panel should have some button for the job queue (so all things related to the printers can be reached from one place). A button under Test and Maintenance sounds good in my opinion.

How could the user masquerade as another user with such a button? Is s-c-p started as root? Anyway: if the user has to enter the root pw (or the sudo pw) for starting s-c-p he should also be able to cancel jobs from other users. Otherwise he should of course only be able to cancel his own jobs.

The fix has been placed under "Applications-Accessories-Manage Print Jobs", but it really should be under "System-Administration-Manage Print Jobs". That's where you find the "Printing" menu. Putting these two closely related apps in separate menus is quite confusing. It confused me enough that I wound up reporting it as a duplicate but (https://bugs.launchpad.net/bugs/151064).

As an addendum to what I wrote just above, I think the menu item should also be renamed. Less confusing (and also shorter) would be:

System-Administration-Print Jobs

This would have the added advantage of being in alphabetical order ("Print Jobs" would appear just above the "Printing" menu item).

Managing a user's own print jobs is not system administration.

As for masquerading: it depends upon the configuration of CUPS. The default upstream CUPS configuration allows masquerading trivially and without a password.
