This Printer requires an Internet connection at all times to work. If you unplug it and want to use it on USB cable offline it will stop printing your documents and print something telling you to connect it back to the internet. If you want to print without an internet connection get the HP LaserJet 209dw. I spoke to HP about this and they said There is no workaround for the 209dwe to print without an internet connection and HP account connect to the printer. PB CAN YOU PLEASE CHANGE The name of this listing or make the "WONT PRINT WITH OUT AN INTERNET CONNECTION" clear and not hidden in the disclaimer right at the bottom of this listing...view more
