XES COMMANDS
General Information
XES commands are used to control the functions of Xerox printers running
in XES mode (also known as UDK, XDPM or 2700 mode). The X/TRA
XLi interprets each supported command and converts it into the PCL5
printer language. This section lists each XES command supported by the
X/TRA XLi and describes how each is implemented by the XLi for use
with PCL5 printers.
XES is an acronym for Xerox Escape Sequence. It is called an escape
sequence because each command in the set is preceded by an escape
character. The escape character is a trigger that indicates that the data that
follows it is not data to be printed but a command to be executed by the
printer.
The escape character is an ASCII 1Bh (27 decimal). Some systems are
unable to transmit this character directly to the printer, so the user-defined
key (UDK) is provided as a substitute.
User-Defined Keys
The user may define a substitute character for the escape character if the
escape character on the host does not transmit properly. The substitute
escape character is known as the user-defined key, or UDK. To define a
UDK, enter the following at the start of a job:
=UDK=character
Thereafter, until the end of the job, or until the user specifies otherwise,
the printer recognizes the selected character as the escape character.
For example, to define the asterisk (*) as the UDK:
=UDK=*
Thereafter, instead of using
s
+B
d
, enter *+B
d
. Instead of using
s
d, enter *d.
NOTE: the
d
symbol indicates valid line end character(s)
