Bi-directional printing is faster than uni-directional printing.
With uni-directional printing, printing is performed only when the print head moves from left to right.

the next line, it prints in a multiple of passes only when the head moves from the right to the left.However,
if there are ruled lines in one line of print, or if the paper feed amount after printing exceeds 1/6 of an inch,
printing is uni-directional from the left to the right.

(*1) Depends on the model
n = 2: Models that use a DC motor for the carriage motor.
n = 0: Models that use a stepping motor (logical seeking) for the carriage motor.
