I think most would agree that HP ink costs are the highest, primarily because they package several colours into a single cartridge. When the first colour has depleted, the whole cartridge must be replaced or refilled.
The 7xxx series printers used various combinations of 56, 57, 58 and 59 cartridges. The 8xxx series printers use different cartridges (94, 95, 99 and 100 in Canada). The newer cartridges are a little cheaper but they contain much less ink.
For example cartridge 57 (cmy), $54, 17ml total volume, $3.17/ml
cartridge 95 (cmy), $37, 7ml total volume, $5.28/ml
Does any one have experience with ink consumption issues with these two series of printers and cartridges?
