The inevitable blowback may solve the problem.  Did eventually with Keurig.  I avoid all things HP except their business-class laser printers, anyway.

Yeah, self solving problem since it's public.  Termination of business if they keep doing it.

Never owned an HP Printer, now I know I never will too.

Seems like creating DRM on equipment that was previously sold without DRM would be legally problematic.  "Other brands may not work" is not the same as "Only our brand will work, we've taken steps to ensure that."  That's the type of thing a purchaser should know up front.

Wonder how may people/companies have a stock of printer cartridges that they already bought which are now useless.

I saw in the 2nd link that one of the other ink/toner suppliers is already preparing to make cartridges that bypass the DRM.  Cat-and-mouse.

Overall it seems like a poorly thought-out scheme, kind of gives me a hint of "desperation".

Actually, the title says it all.

Fortunately my HP printer is so old it needs crutches to function. When it comes time to replace it...no HP printer for this person.

gave up on owning printers years ago as i print stuff so infrequently that the ink will get used maybe once or twice before it's all dried up. far cheaper to do it in the library or whererever. ridiculous that the ink cost more than the printer itself.

No, it's totally logical - the blade and the razor argument. The razor's cheap as chips, the blades (which you should change weekly for a closer, more comfortable shave, natch) not so much...

but it doesn't have to be. it's a deliberate strategy to make cost of ink the primary earner rather than machine, by making cartridges more and more complicated to stop others from selling good old simple ink.

anyway. they backtracked a bit

security issue arises only because they start putting chips into the ink parts. if ink is only ink, there's no security issue aside from on the printer itself. (eg tom clancy, trojans via printers from yonks ago)

The piece of crap plastic is actually cheap as chips.  It's the hardened, finely sharpened blades that actually cost money to manufacture, and are comprised of highly refined quality material.

Ink is dirt cheap to manufacture, by comparison.  Printing companies buy 55 gallon drums of the stuff.  Even really expensive inks are hundredth or even thousandths of the cost of those bloody cartridges.  They're thieves, screwing you as hard as they can because patent laws allow them to make it impossible to compete on their products.

My HP printer is always telling me I don't have genuine HP cartidges in. I just click 'OK' and continue

Well, that was somewhat quick. I do predict they will be more careful in the future. Not that they will not allow this to happen, I just think they'll start selling the printers with warnings that off-brand ink won't work up-front.

Had 2 HP printers and found both drank too much ink, so ditched 'em.  Nowadays I have an Epson, which is economical and a better machine to use than either of the HP ones. 

Thing is, HP wouldn't be the first company to try such tactics to force users to buy their products, and they won't be the last.
