(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)o
must satisfy the condition: 1
s
(n)b
Z 85 (Decimal).
“n”
-
1 is equivalent to 1/72 inch paper advancement. Since the distance bet-
ween any two dot wires of the print head is 1/72 inch, any line spacing in incre-
ments 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. How-
ever, once the code is input, the specified amount of line spacing
will remain unchanged until a code for new line spacing is set.
(Example) To specify the amount of line spacing at 7/72 inches.

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 - (0011000)2), actual output to the Printer is performed
as<lB>~
<41>~
<18>~inhexadecimalcodes.
Keep in mind that the method of input from the keyboard of a host com-
puter is different, for which refer to the specifications of your host com-
puter.
*Example: Input from the keyboard of the TRS-80 personal computer.
