The standard capacity HP 207A magenta toner cartridge has a respectable estimated page yield of 1,250 prints, making it a good choice for those in a small office environment. Whilst those who print more frequently may want to consider the magenta 207X, the Hewlett Packard W2213A is perfect for those who occasionally need to run off a page (or two).The HP W2213A is compatible with several Colour LaserJet Pro printers including the M255nw, but a full compatibility list can be found on this page. Hewlett Packard fully guarantee the 207X magenta directly, should you ever need them, but the quality of manufacture means this is very unlikely.
