HP Printer: How to connect to local network BUT not to internet? (lemmy.world)

I'm using an HP printer and currently am using the USB cable to connect to my PC to print. I'm running out of USB ports and (for some reason) when I use a USB hub with it, my PC fails to read it.

Instead, I wish to connect the printer to my local network, BUT I don't want it connected to the internet. I've seen how dangerous it is to expose your printer to the internet, so I wish to prevent that (plus I don't want the printer to auto-update).

How can I connect my printer to my local network so I can print wirelessly without allowing internet access to it?

If it's important:

My PC is ArchLinux
My printer is a HP ColorJet Pro MFP (I dont know the model #/what series it is)
I do have cups and hp-lip installed on my system

Also: A guest network does not work on my network for some reason, but that's a separate issue unrelated to this.

The simplest way is to just connect it to your network normally, and block its internet access at your firewall (the all in one wifi/router/switch that most people have).

If that isn't an option for you for whatever reason, you can do something like connect it to a raspberry Pi via USB, and have that device act as a print server.
