Of course, one of the benefits of a custom firmware would be, that you can disable such refill checks...

Before each ink cartridge had a chip with an usage counter, it was quite common to refill used cartridges with cheap ink from independent suppliers. (A rather messy task and not sure, how much money we saved by that.)
However that was ready made ink from cheap(er) sources. I don't know anything about making ink yourself. I guess, you at least would need to be careful about health safety during production: Pigments are very fine dust, that you probably shouldn't inhale.

I have been looking into this some 15 years ago, as commercial printer firmwares don't support my requirements.
One thing about laser printers: Even HP wasn't producing the actual printing parts themselves. They import from Japanese companies, that kind of invented it. You could probably buy the same parts and make the rest open-source fairly easily.
Or you pick a popular model (available 2nd hand in quantity) and design an electronics replacement kit for that model.

Yes, this explains this nicely.
I wonder, why you do this? In my experience many replies in very interesting technical threads or other deep discussions between a small group of people won't make it. But random opinion bits will stay around forever. That seems to introduce quite the bias.

Yes exactly. I remember now reading these links. Any idea, why your post disappeared?
I now some people have automatically disappearing posts, but all your others are still present. It seems like a strange #mastodon issue.

Thanks for sharing. It's strange: Somebody (probably @npub1u6n…rger or @npub1m7m…2e7k ) wrote the same back when I posted this originally, but it's gone now and my reply dropped from the thread.
Anyways, here is my reply from back then: https://mastodon.social/@haraldgeyer/113143036090113982

I have written an experimental #mastodon client called #MyAlgo.
It allows for client side (ie under complete control of the user) implementation of algorithms. That is: Users can score and sort the toots in their timeline by whatever they feel is relevant to them.
If you are following more people then you can read, or if you want to spend less time with Mastodon, then MyAlgo might be useful for you.
It is written in python with #mastodonpy:

I remember back then there was a huge demand from people in Europe saying "Give me one as well! I'm paying 200$ and you can give one child one for free." I always wondered, why this never happened.
I guess, your stories of pressure explain this nicely. Thanks for sharing!
