I have an old Brother laser printer that’s been doing fine and doesn’t need to be replaced, but it only supports USB. Is there a device besides an old computer/laptop that would make it a shared wireless printer that supports windows machines well? I’m pretty sure i could come up with something myself, but i would prefer an off-the-shelf solution that handles updates and bugs without needing any attention from me.
Many modern routers have this exact capability - to take a USB-only printer and serve it up over the network. Even some ISP modem/router combo units are set up to do this. Check to see if your router has any USB ports on the back.
Router and printer are in different locations.
You or someone may have an old router with usb in a closet somewhere. Many routers have repeater capability.
