Programming the Epic Edge™
NOTE: This programming guide applies to printer firmware implementing standard
Transact RS232 and USB interfaces. Some printers are configured with firmware that
implement proprietary interfaces and protocols and are beyond the scope of this
document.
The Epic Edge™ printer support multiple methods for TITO ticket generation
Low Level Printer Control Commands
Transact Template Language (TTL)
Legacy Macro Commands
Note: macro command support is provided for compatibility with legacy Epic 950
applications. It is not recommended for new implementations and is not documented in
this manual.
Compatibility Mode.
In order to maintain compatibility with existing applications, the Epic Edge™
automatically adjusts most legacy print data for proper printing with the 300 dpi print
head. Certain operations cannot be adjusted such as bitmap graphics printing. Functions
that cannot be adjusted are noted in their descriptions. The Edge printer defaults to
compatibility mode at power up.
The Epic Edge™ may also be placed in high resolution mode where all commands use
the native 300 dpi x 300 dpi print resolution.
General Programming Information
The first step in programming the Epic Edge™ is to understand how the printer works.
This section covers all the points that need to be understood to program the Epic
Edge™ Printer correctly, including both basic and advanced topics. Since the TTL
contains predefined low level command strings the general information below applies to
all printing methods.
As an ASCII-based printer, the Epic Edge™ accepts 8-bit ASCII characters as both data
and commands. The ASCII table in the Character Codes section shows the relationship
between the 8-bit values and the characters they represent. Most environments either
use the ASCII character table as the default for character values or support an ASCII
mode where characters are interpreted by the ASCII values.
The following subsections discuss general information that is needed for programming
the Epic Edge™ Printer.
