    Post CUPS - Explained

    CUPS is a set of drivers and utilities that provide full printer support, management and usage tools for Linux and other Unix-based OS.

    CUPS provides it's own graphical configuration tools that work through the web. Pont your browser to http://localhost:631
    you may need to give your user or root password, and you'll see the CUPS homepage. From here you can add and remove printers as well as manage print jobs and read the docs.

    The web interface means you don't need any graphicall toolkits installed, you don't even need X running on the computer. You could access the interface through a text browser or from a browser on another computer.

    Isn't that a bit insecure?
    It could be, but the default CUPS settings only allow connections from localhost. You can alter this to allow connections for your LAN (allowing internet access is generally not rocommended) and also control which users access which parts of the coniguration.

    Is MY Printer supported?
    First stop should be OpenPrinting - The Linux Foundation which maintains a list of how well or not each printer is supported and advice on which driver to use. Ideally, you should check here before buying a printer.

    Another one, from lots of people:
    when the printer stalls (paper jam, toner low, other error), its 'stopped'
    in CUPS. When the printer's source of error has been removed, does CUPS
    strat it again ?

    In old faithfull 10.0 it didn't. I briefly tested 10.3, and I seem to have
    noticed a possibility.

    Is it possible in 11, and how ?

    I have never experienced a need to do as you ask. I know what you mean. - But whenever I get a paper jam or ink runs out, I find that page is no longer any use, so just start fresh again with that page.
    You can however pause print jobs can't you.

    I think you misunderstood my point, sorry.

    In short, I meant, is there a way to get CUPS to restart the printer, as
    soon as the printer is longer in error?

    Whithout going to localhost:631, without the need for a CUPS-admin user or
    password.

    The 'OS' in example (Windows, sorry) will retry the printer for a reasonable
    time, before deciding to stop the queue. Say a few minutes. This allows for
    filling up the paper tray, removing a jam, maybe even replacing the toner.

    Arguments against it would, I suppose, include the overhead on the
    connection (USB, network) of those retry attempts. But that's an invalid
    argument to me, considering the speed of today's interfaces and networks.

    And even after that, the user can restart the interrupted job, in the queue
    list.

    So far, in KDE 3. Using releases 10.0 and 11.0 of openSUSE.
    Why, does KDE 4 have a more integrated control of CUPS ?


    > pending jobs etc are here, paused etc also


    Yes, I know. But a stopped printer has to be restarted, using the CUPS web
    interface. At least it had to, on 10.0 and 10.3.

    With 11.0, I didn't do much printing yet. So I was wondering if things had
    changed much.

    OK, I'll have another look at it.
