After I was very skeptical at first due to some bad experiences with other hardware manufacturers, this unit has me absolutely positively surprised! The installation went very smoothly, only for my Vista machine I had to download the latest driver from the manufacturer down load. This device makes it easily possible to access from any PC on the network to a Canon printer (my Pixma IP4300 printer is a). Even bidirectional support functions smoothly, so I am aware of every computer on the current level of each print cartridge. So overall: A great product that's worth 5 stars!
