Format 

PJL commands have 4 types of formats as shown below.    

Format 1  <ESC>%-12345X 

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.
