The NUL code should be input as the command
for the termination ofthe tab set sequence, and the
lack ofthis code will cause incorrect data printout.
1. In case of 5th, 10th and 21st columns.

2. In case of lack of stop position.
[DATA] I ESC DI H H INULI ABC lEIl DEF [!ill GHI [8] JKL @ID [IT]
[PRINT] ABC DEF GHIJKL
3. In case of character data transferring over next tab stop.
[DATA] IESCDI H H H INUll ABCDEF [8II GHI OITJ JKL @ID lIT)
[PRINT] ABCDEF GHI JKl
4. In case of transferring two HT codes at a time.
[DATA] IESC DI H H H I NULl ABCD [8II I SPACE I IT!:!] EFGH [gjJ [];£J
[PRINT] ABCD EFGH
5) ESC E
The ESC E code causes the Printer to print
emphasized characters. Emphasized printing
gives the character a stronger impression on the
paper.
This code can be input in any column position on a
line.
The speed ofthe head carriage reduces to 40 CPS
while printing emphasized characters.

2. [DATA] Isol IESC E I ABCDEFGHI ICR I (ill
[PRINT]
ABCDEFGHI
6) ESC F
The ESC F code cancels the emphasized printing
mode.
7) ESCG
The ESC G code causes the Printer to perform the
double printing. Double printing is carried out in
the following manner:
a) A character is printed.
b) The paper is advanced by 1/216 inch.
c) The print head prints the same character
again.
In this way, the character becomes bold.
