I have installed HPLIP from deb-package with simple sudo apt-get install hplip and installed driver/plugin with hp-plugin.

But the output of hp-check contains errors.
It is known that output of this command is often used for debugging purposes.

The number of errors on clean systems:

| Ubuntu version | Errors |
|----------------|--------|
|    16.04 LTS   |   13   |
|    18.04 LTS   |   14   |
|    20.04 LTS   |   22   |

(number of errors may vary for different flavors)

Is it possible to reduce them to zero?

To reduce the number of errors to zero we need:

  1. Enable Source Code repositories in Software & Updates (software-properties-gtk)

  2. Install build-dependencies and packages:

    sudo apt-get build-dep hplip
sudo apt-get install build-essential libtool libtool-bin libcups2-dev cups-bsd cups-client avahi-utils gtk2-engines-pixbuf xsane

    Some additional packages are also required:

    • For Ubuntu 18.04 LTS and 19.10 -

      sudo apt-get install python3-pyqt4 python3-dbus.mainloop.qt python3-notify2

    • For Ubuntu 20.04 LTS -

      sudo apt-get install libcups2 python3-pyqt5 gtk2-engines-pixbuf python3-notify2 python3-dbus.mainloop.pyqt5

      (but really this is not enough, so I have reported bug 1881401)

  3. Run hp-check again and see

    No errors or warnings.

    message.

And then we can check other possible problems of HPLIP for example with hp-doctor (it contains output of hp-check and other tests).
