(4) ESC A + n (for setting amount of line spacing)
This code specifies the amount of line spacing in the Line Feed, provided that
(n)
D
must satisfy the condition: (Decimal).
“n” = 1 is equivalent to 1/72 inch paper advancement. Since the distance
between any two dot wires of the print head is 1/72 inch, any line spacing in
increments proportional to the distance between the dot wires can be
established.
NOTES: 1. When the POWER switch is turned on or INIT signal is applied to the pin
No. 31 of the interface connector, the line spacing is set at either 1/8 inch or
1/6 inch according to the ON/OFF position of the DIP switch pin 1-1 on the
control circuit board.
2. The ESC A + n code may be input at any position on a line. However, once
the code is input, the specified amount of line spacing will remain un-
changed until a code for new line spacing is set.
(Example) To specify the amount of line spacing at 7/72 inches.
[DATA]
[PRINT)
NOTE: <How to input “n”>
When “n” is actually transferred to the Printer as data, it is transferred in the form
of a 7-bit binary number.
In case of
“ESC A + 24” to specify the amount of line spacing at 24/72 = 1/3
inch (24 = (00011OOO)
2
), actual output to the Printer is performed as <1B>
H
<41>
H
<18>
H
in hexadecimal code.
Keep in mind that the method of input from the keyboard of a host computer is
different, for which refer to the specifications of your host computer.
l Example:
Input from the keyboard of the TRS-80 personal computer.
