DRM in Inkjet-Printers

I recently found out about HP Instant Ink, a service that some people describe as Netflix for Ink.
From https://www.gnu.org/proprietary/malware-appliances.html I quote:
"""
The HP “ink subscription” cartridges have DRM that constantly communicates with HP servers to make sure the user is still paying for the subscription, and hasn't printed more pages than were paid for.
Even though the ink subscription program may be cheaper in some specific cases, it spies on users, and involves totally unacceptable restrictions in the use of ink cartridges that would otherwise be in working order.
"""
I did a calculation and found out that using an old laser printer is cheaper per page than using an HP printer, with or without using instant-ink. Both printers will work using Trisquel, without installing any non-free software.
For the laserprinter I used printer-driver-brlaser, for the HP one, I used hplip. I also found out that the laser printer does not work with the iPhone and iPad. A librecmc router could be used as a translator. Next is trying out to find out how to circumvent the DRM in cartridges, so that ink levels are shown on refilled cardridges.
I have an old Brother laser printer that works great with the regular free cups drivers, but I hardly ever print anything anymore. Maybe about 50 pages a year, and that is on a decreasing trend toward zero. I agree with you, if I needed a printer I would buy a laser printer, maybe a used one that's known to work with free software. I spend about $25 every five years on replacement toner. The cost/benefit ratio compared to inkjet printers is extreme. With inkjet printers, if you don't use them for a long time, you dry out and destroy the jets (or that was my previous experience anyway).
I even used a laser printer to make a Printed Circuit Board (PCB) using the toner transfer method, another advantage of laser printers. Of course I made the design using free software too, most likely KiCad.
