Customer Questions & Answers

I want to use your compatables for my HP Officejet K7100 what is the difference between the 337 and 338 black, what is the difference between 343 and 344 coloured please and what one should i get
The 337 and the 338 are very similar cartridges, which fit most of the same machines (including the K7100), however they differ in how much ink they contain, which affects the value for money. It's a similar situation with the colour, with the 344 containing more than the 343.
