Comments:

Prints out data in the print buffer, then moves the print position one space to the left. Backspacing can be performed up to, but not beyond, the left margin setting. The BS code is also ignored if ESC a, 2, or 3 has been sent. If this code is received immediately after graphics printing, the print position of subsequent data is moved back to the point at which graphics printing started.
