Latest release seems to have been in March 2025. The version you get would depend on how you installed it. For Ubuntu/Kubuntu it looks like maybe they point to the Snap store? I have no idea how well that works and personally would avoid it.

Did you do that, or, download a deb or install “printer-driver-gutenprint” via apt?

In another comment you said you have the Canon proprietary driver. I think you would need the CUPS driver for this to work.

I didn’t do this recently enough to remember what the process looked like. But in your situation I would probably try to uninstall everything print related, reboot, and then start with sudo apt update -y && sudo apt install printer-driver-gutenprint and see where that gets me.

The Gutenprint plugin has support for a bunch of Canon printers. I haven’t used it in a while but I remember it supporting borderless prints with CUPS drivers. Maybe not for all printers? Worth a look at least.

Ah, got it. That plan should be great. You can segment your own wired+WiFi network with that hardware, and even do Wireguard from the hAP ax2 to get whole-network egress via an outside VPN service at a good data rate, if you want.

The other devices you might consider as the router are the GL-iNet Slate series. They will be slower as a VPN router, but they’re pretty small and light. They come with a skinned OpenWRT, but in most cases you can install a build of the unmodified OS if you want.

Sure. That plan would work. You might want to be sure that this is permitted at your university.

Universities often have strict rules about what should connect to their networks.

That isn’t what I would choose for your situation. CRS3xx switches are fast at switching (layer 1 & 2), but not as a NAT router, which you probably need.

Better to pick something from the Mikrotik Ethernet Routers range, assuming you don’t want your personal LAN to have WiFi. The L009 or basic RB5009 are both good options in the same price range. Choosing depends on your upstream connection speed. Both are fanless.

Or pick a Home/Office Wireless device if you are permitted to have your own WiFi access point. The hAP ax2 is small, affordable and performs well at 1Gbps. If your upstream connection is 1Gpbs this is probably what I would choose even if you don’t want WiFi as long as this is enough ports. Just turn off its WiFi radios to use it wired-only. If you have a 2.5Gbps upstream port then hAP ax3 is a better choice.

All the Mikrotik choices will require some learning if you want anything beyond a basic router configuration. But once you get it like you want it they are very solid and reliable.

OpenWRT and OPNSense are easier to jump into without a lot of effort, so if you don’t want a networking hobby I would use one of them. Pick up pre installed device if you want it easy. Or get a mini PC with a few network ports and install the OS yourself to get more power for the money.

How about creating your own LAN within the untrusted network?

Something like an inexpensive OpenWRT router would do fine. Connect all your devices and the server to the router. They are now on a trusted network. Set up Wireguard on the OpenWRT router to connect to Proton so that your outbound traffic from all your devices is secured.
