But, anyhoo, I have a HP Business InkJet 2250 at home... I'll see which ones are low..
The store I was trained at had one, Most of the ones they did were HP and Lexmark/Dell.
Not sure if the Canon or epson were possible on the machine, one thing necessary is being able to fire the jets to test. Every cartridge is tested electronically to ensure they all work inside, then are used on a test strip to make sure they still print correctly.
