This format is only used for the Universal Exit Language(UEL) command.
Format 2 @PJL[<CR>]<LF>
This format allows a PJL line without a command, and is used to break several PJL command lines visually, to
make it easier to see the PJL command lines.
Format 3 @PJL command [<words>] [<CR>] <LF>
This format is used only for the COMMENT and ECHO commands.
Format 4 @PJL command [command modifier : value]
option=value[<CR>]<LF>
This format is used for all other PJL commands.
PJL Syntax Rules:
PJL Syntax should be written according to the following rules.
• "@PJL" must be uppercase. The other words of a PJL command are not case-sensitive.
• Spacing between characters consists of one or more of either the space character (ASCII 32) or the
horizontal tab character(ASCII 9).
• White space should be placed as follows, depending on the location within the command.
w White space must be placed between @PJL and the PJL command name and between the PJL command
and command modifiers.
w If a white space is placed in any other place in a command, it is optional.
w If a white space is not placed between two portions of a command, the command is not valid.
