2-4 PJL Command Syntax and Format
All PJL command lines follow one of the following four
formats. Each format defines how commands using that
format are structured.
<ESC>%–12345X
The only command that uses this format is the Universal
Exit Language (UEL) command.
@PJL [<CR>]<LF>
This format allows a PJL line with no command, and is
used to add clarity to PJL command listings. You can use
one or more of these commands to visually break up several
lines of PJL commands.
@PJL command [<words>] [<CR>]<LF>
The COMMENT and ECHO commands currently are the
only PJL commands using format number 3.
@PJL command [ command modifier : value ]
~ [ option name [= value ]] [<CR>]<LF>
This format is used for all of the other PJL commands and
is described in more detail below.
command — command is one of the assigned PJL
command names, such as ENTER, RDYMSG, or RESET.
[command modifier : value] — The command modifier
enables the user to specify what is effected by the
command. For example, with the command modifier
LPARM you can specify language-specific variables. A PJL
command with a command modifier of LPARM : PCL only
affects PCL-specific settings. A PJL command can contain
only one command modifier. For example, in the command:
@PJL SET [LPARM : personality]|[IPARM : port]
~ variable = value [<CR>] <LF>, you can use either the
LPARM command modifier or the IPARM command
modifier, but not both.
