The Datamax-O-Neil RL4 eliminates the danger of "label mix up" by printing labels at the point of application. And, since workers aren't wasting time traveling to a central location, warehouse operations are far more efficient and productive. The RL4 comes with popular language emulations that allow you to easily replace existing printers in the workplace. The printer is also compatible with most popular WMS packages and offers optional wireless 802.11 and Bluetooth connectivity. The long lasting lithium-ion battery offers maximum power capacity for a full 8-hour shift, even under the toughest conditions.
