Purpose:
This command is used for setting the line spacing, margins, and tabs.

Default:
n = 02 (customer receipt station)
Select 1/8-Inch Line Spacing

ESC 1 or X'1B31'
Remarks:
In the thermal (receipt) station this would set line feeding to 25 steps/line.
In the impact (document - portrait) station this would be set to 6 steps/line.
In the impact (document - landscape) station this would be set to 16
steps/line.
This command should be sent after “Set Print Station Parameters” on
page 130.
Note: For DI portrait printing, characters having a height of more than 9
dots (DBCS 16x16 dots) require a two-pass print, with paper fed
in-between the lines (4 steps). The actual lines-per-inch will be
adjusted. For example, if the printer is set to 1/6-inch line spacing,
the printer will line feed 8 steps in-between each line, and the 4
steps inside of the line. The result is 10 steps per line or 4 lines per
inch.
