ML1190 eco: EPSON LQ/IBM
ML1120 eco: EPS FX/IBM III
> Function:
Prints the data in the print buffer and moves the printhead 
one character to the left according to the character pitch 
set.
> Additional details:
If a Multipass character (e.g. double height character) 
needs to be printed, after the BS the printer performs a 
back space and a LF to the printing position and prints the 
character. (Precise printing position is not guaranteed.)
A backspace code given when the printhead is at the left 
margin is ignored.
Moves back two character spaces if the printer is in double 
width mode.
If clearance between characters is set, BS value will be 
character width and clearance.
In proportional mode:
EPSON LQ – The first character is back spaced by the width 
of the proportional character and subsequently by 10 CPI 
character width (or reduced 12 CPI character width in 
Reduce mode).
IBM – Back space by 12 CPI character width.
