The HP No.300 Black and Colour Combo Pack is one of the most popular ink options for HP users as it is used in a vast array of DeskJet and PhotoSmart printers. These printers are commonly used in homes and small offices because the ink is cheap and readily available. Furthermore, the two cartridge system is a clever way to reduce the number of cartridges used because the single colour cartridge contains all three cyan, magenta and yellow ink. The combined colour cartridge does not mean you have to sacrifice on quality as the HP 300 multipack will print fine quality text and images time after time. Order your new set now.
