Or disconnect the printer completely, attach a rpi to the printer's USB port, and install CUPS.

Network level security is already difficult enough even for professionals, it's nearly impossible to really "secure" consumer grade home networks with tons of random consumer grade devices by trusting one brand and distrusting another.

Personally, I don't see my printer's ink level as some sensitive information. But if I do, I would put it behind auth/encryption.

I connect my printer via USB for this exact reason. Connecting it to Wifi is convenient but just poses too many potential attack vectors. I agree that ink levels are not sensitive information, but a lot of things that you print (or scan if your printer has a scanner too) is sensitive. Given that so many printers are inadvertently accessible on the Internet [1], I'd rather just connect my printer via USB and avoid that issue entirely.

Our home is quite small and so we had to put the printer in another room, hence wifi. I will rethink placement because cable is indeed much better.
