Why mobile? Why now?

The M4L2 mobile thermal  printer improves business workflow efficiency and productivity by allowing end-users to print and apply labels directly at the point of application, instead of running back and forth between a stationary printer and the boxes of products. With the increasingly competitive and efficient warehouse, manufacturing, and retail environments, the M4L2 delivers measurable ROI in worker productivity, errors reduction, and best-of-practice operations streamlining.

What is Dual Antenna technology and why?

A dual WiFi antenna is a pair of identical antennas on the printer intended to increase the WiFi performance by eliminating signal fading and dead spots. This principle known as antenna diversity, offers the ability to use two different reference points for signal reception and transmission, switching back and forth to the better one. A dual antenna on the printer device offers a solution to the problem associated with WiFi fading, dead spots, and drop-outs experienced by single antennas devices. If for instance, one of the antennas falls out of line of sight or dead spot, the printer automatically switches to the other antenna. The printer’s WiFi system will constantly monitors the signal strengths of both antenna and automatically uses the stronger of the two.

What are the major differences between M4L and M4L2?

You say the battery has a life 11% longer than the competition…how long is that?

It is very difficult to give the precise number of hours it will last as the usage of the printer varies based on applications.
