重新发现打印机,Ubuntu 20.04

My network printer (HP Envy 5644) is constantly (2-3 times a day) being added to my computer, even if it's already installed. Earlier I have edited /etc/cups/cups-browsed.conf and changed BrowseRemoteProtocols from dnssd cups to none to avoid this; if I try that now (with Ubuntu 20.04) I end up with no printer at all. Nothing alarming really (and the printer is working), but I don't like the software acting "unfinished" this way. Anyone?
