Genius!! and a similar response to what i was preparing.
"one's made by HP and the other made by Canon"
Sorry, on a serious note to lancybin i believe it is as simple as the ones made by HP are only for HP printers (to my knowledge) and the same for Canon.
On the subject and to try and provide some more useul information to you i would look for "compatible" ink cartridges, especially if your just doing run in the mill printing and even some light photo printing.
