Both Brother and Epson in recent years have released inkjet printers with fill-able tanks instead of cartridges. HP is the only holdout. These inkjets are both cheaper in purchase and ownership, plus the ability to print on photo quality papers.
Yeah it's a bit weird that HP would still be trying to push ink cartridge DRM at a time when many newer printers have moved to ink-tanks where even the first-party ink costs a fraction of the price of cartridges on a per-page basis, and should last far longer between refills. Though HP does offer ink-tank models themselves, with at least some models having been released a couple years back. Canon has them too, so I think all the major inkjet printer companies offer them now.
Those printers do tend to cost more upfront though on a per-feature basis, likely because they are not subsidizing the cost of the printer with future cartridge sales. I suspect that a large portion of people moved to third-party cartridges due to the absurd pricing of official ink that costs almost nothing to produce, and since people are likely printing less in general these days, it probably makes sense for these manufacturers to move to ink pricing models that encourage people to use their printer more, rather than discouraging it. At least with the more reasonably priced bottles of ink, the manufacturers are turning some profit on refills, rather than having it all go to a third-party. They could have done that with cartridges too though. If the cartridges were reasonably priced, people would have less incentive to look for alternatives.
Also, dont put the control chip on the cart, just have dum ink tanks that you can fill with anything, but even then, its likely HP would come up with yet another story about how that too was insecure
I was thinking the same. The main reason the chip is there is to lock out third-party cartridges, not for anything that would really benefit the consumer. I suppose it can also help the printer to more accurately track how much ink is left in a cartridge as well though, since without some unique identifier, the printer wouldn't know whether the cartridge you were inserting was full or not. Though they could probably have a sensor check ink levels through a window on the cartridge or something. And of course, being able to identify a cartridge as genuine could provide the benefit of guaranteeing that the ink is of a formula designed to work well with the printer, and that it might be less likely to leak or clog the print head.
