I experienced problems with a HP Envy 5640 Multifunction printer that had worked perfectly under LL 3.8 but failed to work under LL 5.2. After doing some research I discovered that there is a known and well documented bug relating to several HP Printers and Ubuntu 20.04 which LL5.2 is based on.
The fix is as simple as opening XFCE terminal and then typing "sudo apt purge ippusbxd" enter. when complete, reboot PC and then print test page from printers properties page. ALL functions worked i.e. scanner, print multiple pages to single sheet etc - perfectly for me after following the above instructions and should solve all your issues also
