Chapter 1 — Introduction to IPL Commands

Using ASCII Control Characters

For example, a simple command string can look like:
<STX>E2;F2;T4<ETX>
where:
is the readable equivalent of the start of text character.
<STX>
Command strings must always begin with the start of text
ASCII command code or its equivalent in readable characters.
Readable characters must be enclosed in angle brackets.
For more information on using ASCII command codes or
their readable equivalents, see the next section, "Using ASCII
Control Characters."
is the syntax and data for the IPL command "Format, Erase."
E2
is the command terminator character. Use ; to separate
;
commands and associated data.
is the syntax and data for the IPL command "Format, Create."
F2
is the syntax and data for the IPL command "Bitmap User-
T4
Defined Font, Clear or Define." Because this is the last
command in the string, you do not need to follow it with ;.
is the readable equivalent of the end of text character.
<ETX>
Command strings must always end with the end of text
ASCII character or its equivalent in readable characters.
Readable characters must be enclosed in angle brackets.
All command syntax is case sensitive.
Note: When the printer is in XON/XOFF mode, you can send data and
print multiple labels without using the <ETX> character.
Command strings always include ASCII control characters. To use ASCII
control characters, you can:
• enter a control code. Some word processing programs allow you to
represent ASCII control characters by entering the appropriate control
code.
• type the readable characters. Instead of control codes, you type the
appropriate string of characters enclosed in angle brackets.
For example, an IPL command string must begin with the start of text
control character. The control code for this character is 0x02 (hex notation,
also represented by ^B in some text editing programs), and the readable
characters for this control code are <STX>.
