I always buy ONLY HP ink for my printer. The colors are true & never vary on a page like cheaper ink can do. If you want consistent printing in your HP Printer always buy authentic HP ink.
I have had unlimited frustration with trying to buy the appropriate ink cartridge for my HP 7520. Retail outlets stock each of the other 4 cartridges used in this product, but not the cartridge with the bow tie icon. j Also, the produce I needed was not listed in your online catalogue. I spent considerable time on the phone tracking down this product. It is regrettable when you spend more time servicing a product than you do using it!
