I would make sure to use Google Cloud Print, and restrict all local access to your printer (e.g. can only print via Chrome via Google Cloud Print).

Typically printers will expose more security settings via SNMPv3 and you should take advantage of these (absolutely amazing learning opportunity for up and coming sysadmins/cloud engineers too).

I think HP is highly underrated for their printer security currently. Yes, it’s probably hackable in 5 mins like everything else in that space, but it has signed firmware! And they are the first printer company to be participating in a big bounty saas platform! Good things all around.

Also go with a monochrome black and white printer laser toner to really get costs down. You don’t need color as much as is thought...
