Note: Because the default of the basic calculated pitch is 1/180 for the horizontal direction and 1/360
for the vertical direction, some error can occur, such as position specification, depending on the
print direction. No error occurs if the basic calculated pitch for the vertical direction is set to
1/180 by the GSP command.
