LPT3, replace LPT1 in the example with the appropriate printer port.
Printer Job Language (PJL) commands
See the HP Printer Job Language Technical Reference Manual for a complete description of
PJL commands. This manual is available with the HP PCL/PJL Reference Set on CD-ROM,
part number 5021-0337.
@PJL [Enter]
This command enables the specified printer language. If the printer does not receive this
command it enables the default language. This ensures the correct operation applications
that do not support PJL. The command syntax is:
@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
This command designates the current line as a comment, which is ignored. The syntax is:
@PJL COMMENT <words> [<CR>] <LF>
@PJL INFO CONFIG
This command solicits a response to describe the installed options and allows the printer to
configure the installed options automatically as the applications require.
@PJL INFO ID
This command identifies the printer type to the host for reference when selecting printer
drivers for automatic installation. The command syntax is:
@PJL INFO ID <CR> <LF>
