1. OUTLINE
1.1 Operation Mode
The control commands used on printers covered by this document are comformed to ESC/POS.
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
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.
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$;
