You're welcome. * Some background information.
Recently made an attempt to run Debian unstable on my system. Did a clean install and changed sources.list and upgraded + dist-upgraded. Resulting installation had problems with hplip so I reverted back to Debian stable (another clean install). Subsequently I configured Debian backports and did a apt-get -t stretch-backports upgrade to upgrade installed packages to their newer versions in the backports. Then I noticed that hplip was broken with the same behaviour as in the Debian unstable install. So I did a apt install hplip/stable hplip-data/stable hplip-gui/stable printer-driver-hpijs/stable printer-driver-postscript-hp/stable to revert to stable hplip and it again works fine. * Testing/Unstable Don't require the testing/unstable version for hplip. Stable works fine. But will it (still) work in the future version of Debian? (That's why I submitted the bug report). * Reproducing If hplip 3.18.12 works fine at your system I don't know how to reproduce the problem. I do have sudo installed and my account added to the sudo group to enable. But when hplip asks for a password it has 'root' already filled in for the username (grayed out so it cannot be changed) so I typed my root password in the dialog window. Thanks for the follow up.
