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.
- White space should be placed between @PJL and the PJL command name, and between the PJL
command and command modifiers.
- If a white space is placed in any other place in a command, it is optional.
- If a white space is not placed between two portions of a command, the command is not valid.
