Why was my HP printer automatically shared on my WiFi?

fr flag

I got a pleasant, but odd surprise today. I went through the whole rigmarole of installing HPLIP on one of my laptops, finally getting an ENVY 5644 working with duplex, colour and everything. Having a number of laptops at home, I dreaded having to go through this again and again, but lo and behold, I didn't need to! For some reason, the printer was automatically shared to the other machines! Granted, I like to keep my computers as a tightly knit family (passwordless ssh, filesharing via sshfs for example), but this printer sharing was utterly unexpected! I have NOT flagged the printer as shared, thus the surprise.

Anyone here with an idea as to why I got this lovely surprise today? (All machines running Ubuntu 21.04 BTW...)

Is the printer directly connected to your laptop or is it connected to your home network?

@Nmath This is a network ptinter, so only the home network. I needed a USB cable to set up the HPLIP system, but that was only temporary.

CUPS is using the Internet Printing Protocol https://en.wikipedia.org/wiki/CUPS

When one computer is set up for a printer, other computers connected to the same common network can do print jobs. I.e. if the "printer computer" is running.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
