    help please, trying to install printer, need help manually installing dependancy

    Thank you for reading this!
    I Have just installed kubunto. I have an hp printer that doesnt seem to work on multiple linux installs. other hp printer does.

    I just manually installed hplip-3.19.12.run
    ​

    after that I got this message in console
    RE-CHECKING DEPENDENCIES
    ------------------------
    error: A required dependency 'python3-pyqt4 (PyQt 4- Qt interface for Python (for Qt version 4.x))' is still missing.
    error: Installation cannot continue without this dependency.
    error: Please manually install this dependency and re-run this installer.

    in process of installing pyqt 4 at the end i get this

    Reading package lists... Done
    E: The repository 'https://ppa.launchpadcontent.net/rock-core/qt4/ubuntu jammy Release' does not have a Release file.
    N: Updating from such a repository can't be done securely, and is therefore disabled by default.
    N: See apt-secure(8) manpage for repository creation and user configuration details.

    i have tried 2 different ones and this happens both ways. what should I do? I am super slow and new to this.

    You seem to be trying to install an old version of hplip that is using very old dependencies that no longer exist - pyqt4 and Qt4 are long deprecated.
    The PPA you added does not contain packages for 22.04, only for 20.04.
    You need to remove it, it will show this error every time you update.
    sudo ppa-purge ppa:rock-core/qt4


    Which printer model?
    hplip comes installed with Kubuntu, 3.21.12, or rather most of the parts, including driver files.

    It does not come with the GUI utilities.
    You can install this manually, though it will not add support for more printers.

    Use Muon Package Manager to find and install hplip-gui
    or
    sudo apt update && sudo apt install hplip-gui

      HP laserjet P1102w its probably 7 or 8 years old but still works awesome and I have more toner for it. our other all in one printer can be sketchy at times, but the children use it for school.

      in muon, it shows hplip installed

      when i go to config printer screen, under driver it lists the printer, then hpcups 3.21.12, requires proprietary plugin

        Ok, follow the instructions at the bottom of this page:
        https://developers.hp.com/hp-linux-i...ry_plugin.html
        You printer requires some proprietary bits that can't be included in the open source stuff.
        But they have a GUI tool that will walk you through things.

        Basically enterhp-setup​ in a terminal to open it, and follow the directions.
