1. OUTLINE
1.1 Operation Mode
Our printer has ESC/POSTM as control commands.
1.2 Character Set
All print data sent from the host computer to the printer are automatically converted to one-byte alphanumeric or
katakana characters (ANK) or two-byte Kanji corresponding to the characters and symbols.
NOTE: For the contents of character set, refer to Character Code Table of this document.
1.3 Control Commands
1.3.1 Control Command Details
Control Commands are used for controlling the operations of the printer such as starting/stopping of printing, line
feeding, paper feeding, etc. They control all functions related to printing, such as type of characters, enlargement
of characters or setting of format.
1.3.2 How to Send Control Commands
Some methods are available for sending Control Commands from the host computer to the printer. Here, a
method of sending by BASIC programming is explained.
Example 1
Let’s print a character string “CITIZEN” in enlarged (double-height, double-width) and in normal format.
Program coding
The Control Command shows that the command name for setting the size of a character is GS !. Let’s make a
program using this code. An example is shown below.
Program List Print Result
10 A$="CITIZEN"
20 LPRINT CHR$(&H1D);"!"; CHR$(&H11);
30 LPRINT A$;
40 LPRINT CHR$(&HA); CHR$(&HA);
50 LPRINT CHR$(&H1D);"!"; CHR$(&H00);
60 LPRINT A$;
70 END
CITIZEN
CITIZEN
In lines 20 and 50, setting and canceling of enlarging a character is sent. As a result, lines 30 and 60 print the same
character string but line 30 prints enlarged characters and line 60 cancels the enlargement and prints in normal
format.
* In this document, sample programs are in BASIC. For details of BASIC programming, refer to the manual for
BASIC.
