If you need reliable, unfettered remote printing capabilities, this module is the product for your office. It's as fast or faster than printing from a network. Even simultaneous and multiple print requests aren't a problem. The sharer's built-in printer manager handles print requests if the designated printer is busy. The frequency is so high that radios, cell phones, computers, electronic equipment and other devices won't affect transmission. You don't even need a clear line of sight to print. This unit transmits through walls, floors, and ceilings.
