Quality died long before Harper.
The ink chip thing would have happened regardless what party or leader sat, unless Parliament had nothing better to do so look into the anti-competitive nature of printer ink chips, and ban/control it in a fashion to allow 3rd party clone or remanufactured cartridges, and user refilling.
Nb: From what I see there are two basic chip methods printer manufacturers use.
HP and Lexmark simply have a serial ID code on the chip in the cart. The printer monitors what carts have been used an how much, and hold only so many cartridge IDs. As you use new carts, old ones get dropped of the list, and theoretically you can use those carts again, with the printer none the wiser.
Canon and Epson store usage and a serial code on their secure chip. With Canon, you can tell it to ignore the chip count at your own peril. I am not sure of other manufacturers.
Some laser cartridges have, or had, a fuse which is blown.
