Hewlett Packard are know for creating top-quality reliable products, like the F9J95A ink cartridge, that work flawlessly with your inkjet printer. Whilst the genuine HP 745 is nothing new in this respect, the fact that it carries 130ml of incredibly durable magenta ink is.The presence of original Hewlett Packard ink is particularly important in the HP Designjet series of printers for which the F9J95A was designed. The HP Designjet Z5600 44-in PostScript Printer (and all other compatible printers) are ideal for producing high quality artwork and deserve to have original magenta ink cartridges installed within them.
