Set Line Spacing to n Minimum Units
Sets the line spacing on the selected station:
•
Receipt station: n/360 of an inch
•
Slip station: n/144 of an inch (on some models, the command may not affect the slip
station)
The minimum line spacing is 8.5 lines per inch. The line spacing equals the character height
when n is too small.

Return Home (Slip Station)
Moves the impact printhead to the home position (beginning of line on the left side). If the
printhead is already in the home position, it is not re-homed.
As the 7156 is able to detect carriage motor jams, the printhead does not need to be homed
after each receipt. The Epson TM-930™ homes the printhead after each receipt because it is
unable to detect carriage motor jams.
