Set Left Margin
ASCII Code ESC l n
HEX Code 1B 6C n
Where n = number of columns from the left edge of the physical page to the
beginning of the print line.
Purpose Sets the left margin to n columns in the current font.
Comment Be sure to use lowercase l (as in left) instead of the numeral 1 (one)
for this command. The number of inches of margin does not vary if
the font, character width, or horizontal dot density changes. This
command automatically clears and resets horizontal tabs to every
eight characters, then performs a CAN operation. The smallest
possible space between the left and right margins is the width of one
double wide 10 cpi character. If a margin control code violates this
minimum distance, it is ignored.
