Review on HP 305A CE305AQ1 4 Toner-Cartridges for HP LaserJet Pro Color M451/M475/M375nw by Mike Sevenfourgd

The print quality is excellent, but the toner is very expensive. If you need to print a large batch (e.g. 800 pages or more with lots of colors) it will take no more than two or three days. So it's not a printer that anyone can use whenever they want. You should keep track of how often it is used. This ink should last at least a year assuming you don't need to print a lot which relies heavily on color inks.
