I've heard Canon is the worst for "monitoring" their cartridges, but I've learned how to fill my own (2 bottles - 4 refills - $20) and how to over ride the error message that says my cartridge is out of ink and won't let me print, when I know darn well it isn't! LOL!!
I dumped my HP printer that used ink cartridges and went to Laser Jet, that uses a large cartridge of powder, it lasts for months, you get 4000 copies out of 1 cartridge,
