A:Answer The HP 3755, as is common in most wireless-print-capable equipment, requires that the device(s) from which you are printing are communicating on the SAME wireless/wifi network as the printer. You may need to download/install the setup software, which is included in the box with the 3755 printer. Once all of your devices are setup to "communicate" with the 3755 AND both the 3755 printer and the computers, smartphones, tablets, etc., are all on the same wireless/wifi network, you'll be able to print from all of them to the 3755.
