How Do Printer Sharing Devices Work for Multiple Computers?

Hey everyone! I'm trying to set up a printer sharing device so multiple computers in our office can access the same printer. I’d love to understand a bit more about how these devices actually work. Do they connect through USB, or do I need a network setup? Are there any reliable models you’d recommend that are user-friendly? Also, do I need to install special software for each computer, or will it work automatically once connected? Any tips or experiences with setting up printer sharing devices would be super helpful. Thanks!
