Get a tank printer, you can’t DRM liquid (afaik). I have an hp one with tiny tanks, I refill once a year and the branded bottles aren’t too expensive, but you can use generic inks, though I’ve read about people with the same printer having problems with the viscosity of generic inks, so you still need quality ink.

A downside is I have to print something every now and then to keep it from clogging (a month or two).

I don’t necessarily recommend my specific model, but at least that type of printer, I’ve found it’s been great. Software is kinda shit like any printer but I have Linux on my desktop so it doesn’t really matter, shitty proprietary software is only needed for Windows (I have zero experience with Mac)
