2-8 Thermal Head
1) Function
This unit utilizes state of the art thermal printer technology.
In this format, the recording paper (roll paper) is chemically treated and heat sensitive.
When the thermal head contacts this paper, the "Black" signal comes from the forwarding side, the
thermal head emits heat momentarily and black dots (appearing almost as a point) are printed on
the paper.
If this point is continued, letters and/or diagrams appear.
