I do allot of printing. My 479fdw is a good printer for someone who does not da allot of printing. If you do 20,000 copies a month, this unit cant handle it. Cools down to many times during the printing process and if you want to print just a few selected pages out of 150 pages it just prints the whole set again and the ink is expensive.
I have a HP Color LaserJet Pro M478f-9f, which uses these HP Toners. I buy only the High Yield cartridges because they last about 3 times longer than the regular yield. Image quality in black and white as well as color are great. I am very pleased with this Color LaserJet Pro. I have been using only HP LaserJets for more than 25 years.
I bought one cartridge each of three colors and black. The total price was significantly more than the printer cost. This is not a way to encourage returning consumers to purchase HP products when considering a printer upgrade or update.
