Better to get Canon's own ink,
Verified Purchase(What is this?)
This review is from: Canon Pgi-550xl High Capacity Ink Cartridge - Black (Office Product)
Last week I was printing out stuff from my computer, the black ink 550xl ran out. I had a cheaper replacement but when I put it in my printer it was not recognised. I was unable to do my work. Since then I've noticed the Canon xl ink is 22 ml but the cheaper inks I have are only 7ml.
For me it makes sense to buy the Canon version of the inks.
