The combination pack saves money as compared to purchasing the cartridges separately. Since I use my printer for photos printing as well as text it seems that I go through all the colors and black at the same rate. The cartridges are easy to install. I have tried to used discounted compatible cartridges but these did not work with the HP office-jet pro 8600. I have been waiting for sales from Staples in order to save money on the ink and so I keep one in back up at all times and therefore avoid having to buy them at the last minute at a higher price.
I use HP ink products for my business in printing documents on my HP OfficeJet Pro 8600. In past years I would try recycled cartridges at cheaper prices but would never do that again. HP products are by far the best on the market and the ink cartridges are no exception. The ink quality is great and the page capacity is exceptional. HP ink prints well in black and the color ink is always clear and vibrant. Printing on plain paper photo paper and heavier stock works well with the 950 and 951 cartridges.
When my old printer gave out I really needed a reliable printer and decided to get an HP Officejetpro 8620 with the legal size scanning bed. This is one great printer. And the ink is fantastic! It might seem a bit pricey at first but it just looks great whenever I have to print anything in black and white or color. The blacks look very black--as they should! And the colors look bright and saturated--just as they should too! The printer does a great job and prints with great speed! I'm so very very pleased with this printer and how good things look. The ink is well worth every penny! And the cartridges are easy to install. Overall this is a great printer with great results!
