Do you believe everything you see in such a biased video? (it's practically a documentary on bias ...)
First we see the guy driving the printer (which is apparently filled with heavy lead) on a cart to his "workshop" (completely pointless scene). Next he claims the printer is set to stop working a fixed number of prints, without showing any proof. Printers require maintenance because they contain parts that wear down. The document which is barely shown in the video indicates the expected performance, as per the design. Counters may be kept for certain parts to alert the user to a part needs to be replaced (CRU or FRU). On many printers this kind of alert (which sometimes prevents printing) can be reset, without actually replacing the part.
Printer vendors make their profit on the ink cartridges/toner, not the printer itself. In some cases, printers are cheaper than a single set of ink cartridges. No wonder they take (unlicensed) third party ink suppliers to court ... Anyhow, when your printer breaks down, you'll likely be slightly upset and may be reluctant to buy from the same vendor again (printer AND consumables). This is something they'd want to avoid, right?
