hi
today i noticed printing was broken on my plasma installation, printing from kate just prints out gibberish, the same from other kde apps, oddly from system settings > printers >maintenance > print test page it comes out just fine
i also tried printing a page in firefox, works just fine
i also booted eos gnome (which i installed to test gnome 43, on a separate drive) and printing works great
i did check both the printing and hp boxes in calamares when installing. this is a hp laserjet m14, usb connection
