Control Codes Overview
This Programmer's Guide is designed to help users of the EPIC 3000 printer develop
applications. EPIC 3000 Printers are specialized point-of-sale printers that have several
features not normally found on general-purpose printers. Because of these special
features, EPIC 3000 Printers have unique control codes. This programmer's guide
documents the control codes that are unique to the EPIC 3000 Printer.
Nomenclature
When describing control codes, confusion often occurs as to whether the description is
decimal, hexadecimal, or
ASCII. To minimize the problem, this programmer’s guide uses
the following nomenclature when describing control code sequences.
[ ]
Encloses a control character. [ ] represents a single, 8-bit value as
defined in the standard ASCII tables. The ASCII Code Table in Appendix
B lists the control codes. An example would be
[ESC], which would
represent a 1BH or 27 decimal.
< >
Encloses an 8-bit value in decimal format. The value is from zero to 255.
An example is <2>, which represents 02H or 2 decimal.
<n>
Indicates a variable parameter. The variable parameter, <n>, can have a
value from zero to 255. The meaning of <n> is described and defined in
the description of the command.
<n
1
> <n
2
>
Indicates that there are two parameters, <n
1
> and <n
2
>, where both can
have values from zero to 255.
<m
1
> <m
2
>
Is an Ithaca
®
Printer Control Language (IPCL) parameter consisting of
two digits where <m
1
> and <m
2
> are ASCII characters from zero to nine.
The parameter is combined to form a value from zero to 99. If <m
3
> is
included, the parameter is combined to be from zero to 999. If two values
are specified, there must be two bytes added to the IPCL code. That is, if
the command specifies <m
1
> <m
2
> and the desired value is five, it must
be specified as 05.
x
All other characters in control strings represent ASCII characters. For
example, [ESC] 1 represents 1BH followed by 31H.
In many cases, applications require that control sequences be specified in hexadecimal
or decimal codes. In most cases, commands are specified in ASCII, hexadecimal, and
decimal. The ASCII Code Table in Appendix B (page 252) lists ASCII, hexadecimal, and
decimal equivalents.
Standard Emulation
The standard control codes for the EPIC 3000 Printer are extensions and subsets of the
PcOS IBM emulation provided on other Ithaca
®
products. In some cases, an application
