Libre office is having issues, constant overriding settings and refusing to print duplex pages on printers that can print double sided is more than annoying, it is worth uninstalling garbage that doesn't work. Worked in 21.1 mint 21.2 stopped printing double sided and in 21.3 it still refuses to print duplex pages. all settings were set and worked then it updated and started printing only single sided pages.congrats grade "F".
