Both my girlfriend and I are both teachers and must accordingly much print - the HPler makes this impressive! We had are prep a HP All-In-One from Aldi - cheap in the purchase but high in consumption. After ~ 160 pages was concluded with the XL cartridge. Even better: The Pro 8600 prints between 1000 to 2000 pages for the same cartridge price and is always reliable! Color prints are okay, but not a highlight - for school or statistician, it is sufficient but not completely out. There is also next to the duplex printing various apps (gadgets), with which you can print out the weather or news, for example. Especially cool: The printer only supports AirPrint (print via smartphone) also ePrint: This means that I can send from anywhere traveling documents to an email address that is connected to the printer and when we get home, the files are already printed in our print professionals. From us the machine obtains an absolute and perfect buy recommendation!
