Universal Exit Language (<UEL>) Usage
The <UEL> Kernel Command signals to the printer that a PJL job needs to be
processed or has completed processing. This allows the printer to switch
between PJL and its default printing language (for example, PostScript). The
following bullets identify the rules you should follow when using the <UEL>
Command:
Always start and end all PJL jobs with the <UEL> Command. The Syntax
for this command is
<ESC>%-12345X
The <UEL> Command at the beginning of the PJL job must be immedi-
ately followed by the @PJL prefix. No spaces or other characters can be
placed between the <UEL> and the @PJL characters. For example,
<ESC>%-12345X@PJL
Following the text shown in the above example, you can continue
with a <CR> <LF> to begin another PJL command on the next line,
or you can use the @PJL on this line to start another PJL Com-
mand.
No characters should follow the <UEL> placed at the end of the PJL job.
Any character after the <UEL> is seen and handled as a new job.
Additional Syntax Rules
The <LF> (Line Feed) control code must be used at the end of each PJL
command to terminate the line.
The only exception to this rule is the <UEL> command, which does
not require the <LF> control code.
The <CR> control character is optional, but can be useful when spacing is
needed between command lines (no blank lines are allowed in PJL jobs).
Always place the optional <CR> before the <LF>, which is used to termi-
nate the line.
A space (ASCII 32, Hex 0x20) or tab (ASCII 9, HEX 0x09) is required
between the @PJL prefix and the PJL command name.
A space (ASCII 32, Hex 0x20) is required between the PJL command
name and command arguments.
