I have been using HP products for several years and now have two of the HP Office Pro printers. I love the ink cartridge that HP has now you can purchase the XL size and it just seems like you can print forever before you need a replacement cartridge. The color is true and things look professional when printed. The ink is one of the best I have found. I do a lot of pictures and they look great the ink is fast drying. Staples has the used ink cartridge program and I love to turn in 8 - 10 cartridges for credit at $4.00 a piece. That is a great program for customers.
I attempted to save a few bucks by buying non HP ink. This was a big mistake! That ink worked well for a few weeks then the black failed after using only about half. I replaced it with HP ink my printer worked great again. Then the color ink started to fail and produced poorly mixed colors. I then went back to Staples and bought a fresh package of all HP inks. No more printer problems and my printing is again accurate and colorful. I will never be tempted to buy off-brand ink again. My advice is to buy and use only HP ink. It is less expensive in the long run and much more satisfying.
