resolution.

Auto CR
When auto carriage return is set to On, each line feed (LF) code
is accompanied by a carriage return (CR) code so the printer
moves the next printing start position to the left margin. When
this setting is set to Off, you must send a CR code after the line
feed code to move the printing start position to the left margin.
Columns
You can select the number of columns in one line.
TOF position for PR40+
When you select On in this option and PR40+ in Emulation, the
top-of-form position is set to 6.5 mm which is unique to the PR40+
mode. When you select Off and PR40+, the top-of-form position
is set to the same position as in the PR2 and PR54+ modes (the
factory set default is 4.2 mm).
