Chapter 7 Print Control Codes

(18) Specifying the line feed amount (ESC 3 n)
Code: [1B] h + [33] h + n
* (0 ≤ n ≤ FF) Data are expressed in Hex code.
This command sets the line feed amount per line in [n x basic calculation pitch] inches.
• Sets the line feed amount for a set sheet selected by ESC c1.
• The line feed amount can be set independently for the receipt and journal printers,
but if printing of the same data by both the receipt and journal printers is specified,
and printing is done in the Page mode, the line feed amount set for the journal
printer is disregarded and the amount set for the receipt printer is made valid.
• The line feed amount can be set independently in the Standard mode and the Page
mode.
• The basic calculation pitch is set by GS P. Also, once the line feed amount has
been set, it does not change even if the basic calculation pitch is changed by GS P.
• If there is a fraction as a result of calculations, interpolation is carried out at the
mechanism's minimum pitch. Remainders are cut off.
• In the Standard mode, the basic calculation pitch (y) for the vertical direction (pa-
per feed direction) is used.
• If used in the Page mode, movement from the starting point is as follows.
(1) If the starting point is specified as “top left” or “bottom right” by ESC T, the
vertical basic calculation pitch (y) (the paper feed direction) is used.
(2) If the starting point is specified as “top right” or “bottom left” by ESC T, the
horizontal basic calculation pitch (x) (perpendicular to the paper feed direc-
tion) is used.
• The maximum line feed amount that can be set is 40 inches. Settings that exceed
the maximum value are rounded to the maximum value.
• The initial value is a line feed amount corresponding to 1/6 inch.
