The Hewlett Packard Envy 7640 takes the HP62 ink cartridges. You can choose from compatible cartridges or genuine HP cartridges from Affordable Ink. Compatible HP62 cartridges are significantly cheaper than genuine Canon cartridges with the price of a set of cartridges being close to the price of a single genuine cartridge.
The ink capacity of a compatible and a genuine cartridge are the same. In our experience there is no noticeable difference in print quality between a genuine and a compatible cartridge.
Genuine cartridges are reliable and are likely to work every time. Compatible cartridges are a much cheaper alternative to genuine cartridges and we guarantee the compatible HP62 cartridges will work in your Hewlett Packard ENVY 7640 printer or we will refund your purchase price in full.
