That doesn't help all the people who bought HP before they knew this "feature" would activate at a later date.
in fairness most who actually research a printer will steer clear of them as HP are one of the worst and have been for a long time, it is folks who bought it due to sale price or it was the first thing they saw in store etc who'd been burned most likely. Canon and Epson are the only two in the game really and even then you need to research and be careful what you install. With decent aftermarket ink and good resetter etc the right printers from those two companies tend to be fine for their life. I've been through several canon ip4500/4600/4700 that I've printed massive amounts through to the point I had to replace them due to not being worth servicing past a certain point; I'd change waste ink pad and use fw hacks, new print heads and so on a couple of times before death but cheap enough to replace once they are knackered. My pro-10 is still doing fine but I steered clear of the next model up I was going to get as the Pro-1 waste ink and the extra greys didn't make a difference big enough to put up with that. Similar things with epson and some I've dealt with in past or friends who run them are a dream with CIS setups but some models are nightmare to operate like that.
