1. INTRODUCTION
The EPM203-MRS is a 2 inches, 3V, Easy Loading Printing Module with an integrated control board
using serial and parallel communication protocols.
The EPM module consists of a set of mechanical and electronic parts.
These parts have been designed to have a high grade of integration and to perform many different
functions.
The sections that form the EPM module are described in the following image.
1. Printer mechanism, easy loading type
2. Paper roll housing
3. Cover group, with Lever (for easy opening) and Roller
4. Tear Bar, for paper cutting
5. Control panel with two push button and one LED
6. Electronic Control Board
