I thought printer makers had woken up to that years ago and now only supply "starter" cartridges with their new printers, with only a few hundred pages worth of ink inside.I hate to say it, but It's usually cheaper to just buy a new printer than refill the ink. I end up just buying another printer and throwing the old one out or giving it away. I had a really night cannon photo printer that could print 11X17 AND refillable tanks but it had 25pin serial connector so once the computer I printed from died it had to go. Thought it would be easy to replace it but then I deal with all the printer shenanigans and just throw them out. I especially hate the cartridges that have chips in them that once the run out of ink they 1) are killed and can't be refilled and 2) stop you from printing in black and white because one color is out. Why is it so hard to find a good printer with refillable cartridges at an affordable price?
Not sure if it generally applies, but years ago HP were also geoblocking their ink cartridges. A legitimate HP cartridge bought in Asia would not work with an Australian bought printer. Then there's their old trick of reporting the cartridge as empty when there was still 10% to 20% of ink remaining.
