The PR 4 prints using a dot matrix, impact print-head. A step motor advances the head along
the printing line with a resolution of 1/75".
Printing is bi-directional, with print path optimization.
The distance between the print head and the print contrast plate is automatically adapted to
the paper thickness by means of a spring mechanism.
