E-Class DPL Programmer’s Manual 5
Control Codes
Introduction
The printer requires a special “attention getter” character in order to receive a command sequence,
informing the printer that it is about to receive a command and the type of command it will be. Control
Commands, System-Level Commands, and Font-Loading Commands have their own unique attention
getter, followed by a command character that directs printer action.
Attention Getters
The attention getters (e.g., SOH”) are standard ASCII control labels that represent a one character
control code (i.e., ^A or Ctrl A). Appendix A contains the entire ASCII Control Code Chart.
Attention Getter For: ASCII Character Decimal Value HEX Value
Immediate Commands
SOH 1 01
System-Level Commands
STX 2 02
Font-Loading Commands
ESC 27 1B
Table 2-1: Control Code Listings
Alternate Control Code Modes
For systems unable to transmit certain control codes, Alternate Control Code Modes are available.
Configuring the printer to operate in an Alternate Control Code Mode (selected via the Setup Menu or
the <STX>KD / <STX>Kc commands) requires the substitution of Standard Control Characters with
Alternate Control Characters in what otherwise is a normal datastream.

See Label-Formatting Commands, ^, set count by amount.
Table 2-2: Alternate Control Codes
Note: Throughout this manual <SOH>, <STX>, <CR>, <ESC>, and ^ will be used to indicate the
control codes. The actual values will depend on whether standard or alternate control codes
are enabled for the particular application.
Alternate Line Terminator
Alternate-2 Control Codes provide for substitution of the line terminator as well as the control characters
listed above. The line terminator <CR> (0x0D) is replaced by | (0x7C). The following is a sample label
format datastream for a printer configured for Alternate-2 Control Codes:
~L|1911A10001000101234560|X|~UT01ABCDE|~G|
