What brand of printer sells the cheapest cartridges?
When trying to calculate the cheapest cartridges, price per cartridge isn’t always the correct determination. You have to look into cost per print, for example, if an Epson cartridge costs $10 and you get 120 prints and an HP cartridge costs $30 and prints 500, then your $10 cartridge actually winds up costing you $50 for the same amount of printing so the more expensive inkjet cartridge is actually $20 cheaper.
