flatpak version does not recognize printer
I am running an up-to-date KDE Neon Linux (i.e., ubuntu LTS + rolling KDE updates: Plasma 5.12.3, Qt 5.10, Kernel 4.13.0-37) with which I cannot install MuseScore 2.1.0 via the official repositories due to a dependency issue. I assume that this problem is similar to the one described here: https://musescore.org/en/node/97261 Compiling from the source works fine. Anyway, because of this issue, I tried the alternative installation options: flatpak, snappy and AppImage.
I have a problem with the flatpak version of MuseScore: it does not display my (network) Samsung printer in the printing dialogue. The only option is Print to File (PDF). With the AppImage version, the printer shows up correctly. With the snappy edition, I had to
sudo snap connect musescore:cups-control to make it work, as explained in the installation instructions. The binary compiled from the v2.1.0 tag from the git repository works fine, too. So I assume the problem is with the flatpak package. The printer has been added via the KDE system settings module "Printers".
Should I file another bug for the broken dependency issue on Neon desktops?
