They use the small flash inside the DRM chip in the cartridge to store the telemetry, then the e-waste companies are paid by HP to read and send to the mothership the contents of the chips sent to recycle

Don't know about months. we print once or twice a week, with some spells where we print dozens of jobs on one weekend. But so far we had way less issues than with HP. Occasionally, it did a head clean.

With the last set of cartridges on the HP, they basically went into the head cleaning dump - with a two page color print, the second page lost color, and it needed a deep clean to come back. And returned to the problem when I printed the next batch half an hour later. Basically a 100 quid cardridge set for printing maybe 20-30 pages with color. And it was not even full page color, but a set of 15 cards on a page, each with a small picture of the item.
