From the article: He cited a Wired report that said HP “has long installed a security chip in its cartridges and printers.”
“If you use knock-off cartridges, you’ve probably seen a warning at some point that it isn’t HP-approved. Annoying, but that’s about all,” Wired said. “Last year, though, HP implemented a firmware update in enterprise printers that, as of last week, locked out any cartridges but its own. As the company says, ‘other cartridges may not function.'”
I don't print.....ever. But some of you guys might find this usefull:)
Comes as no surprise as many companies are endeavouring to 'lock' the retail-consumer into their environment ('walled garden')
But this approach by HP can also backfire, even though this 'non-HP cartridge blocking' is directed at enterprise users, people / businesses can vote with their wallets, and chose another printer brand.
I actually work with HP Printers, and refill cartridges they try this shit every 2 to 3ish years....and there's always someone to override said "firmware" and from the programmer we use it's actually quite easy. All our programmer does is read the chips and doups them and makes the printer think it's genuine.
Look at the laws, they can't legally stop people from using non HP cartridges.
It's just a marketing / PR scam to try and scare people into buying Genuine HP Carts.
