Variable Size Line Feed ESC J n
This command moves the paper forward as per the distance specified by the parameter n x 0.125mm. 0 ≤ n ≤ 255.
A Carriage Return (CR) is also performed to place the current print position at the beginning of the next line.
Example: The following escape sequence advances the paper ten millimeters. Each dot is 0.125mm so to advance the paper
10mm, the n parameter is 80 (10 / 0.125).

Decimal: 27 74 80
Variable Size Reverse Line Feed ESC Q J n
This command moves the paper in reverse direction as per the distance specified by the parameter n x 0.125mm. 0 ≤ n ≤ 255.
A Carriage Return (CR) is also performed to place the current print position at the beginning of the next line.
Example: The following escape sequence moves the paper in the reverse direction ten millimeters. Each dot is 0.125mm so to
reverse the paper 10mm, the n parameter is 80 (10 / 0.125).
