@PJL [Enter] LANGUAGE = {PCL/PostScript} [<CR>] <LF>
UEL (universal exit language)
This command (also referred to as the universal exit language command) terminates the
current printer language and returns control to PJL. It performs the following actions:
● Prints all data received before this command.
● Performs a reset: <esc>E in PCL, <cntrl>D in PostScript.
● Turns control over to PJL.
This command is also a valid HP-GL/2 terminator.
The UEL command must be immediately followed by the “@PJL” command prefix.
Characters or control codes other than @PJL (such as <CR> or <LF>), enable the default
language and process the print job in that language. All jobs must begin and end with the
UEL command. Besides entering PJL, the UEL command has the same effect as the
<esc>E command. However, the <esc>E command should always be included to ensure
backward compatibility.

@PJL COMMENT <words> [<CR>] <LF>
