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
immediately 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 Command.
!
No text can follow the <UEL> placed at the end of the PJL 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
terminate the line.
!
A space (ASCII 32, Hex 0x20) or tab (ASCII 9) 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.
