Universal Exit Language Command

The Universal Exit Language (UEL) command causes the PCL printer language to shut down and exit. Control is then returned to the Printer Job Language (PJL). Both PCL 5 and HP-GL/2 recognize this command.

?% – 1 2 3 4 5 X

	Default	=	N/A
	Range	=	–12345
	This command performs the following actions:
	z Prints all data received before the Exit Language command.
	z Performs a printer reset (same effect as ? E).
	z Shuts down the PCL 5 printer language processor.
	z Turns control over to PJL.
Notes	Hewlett-Packard strongly recommends the use of both ? E (printer
	reset) and ?%–12345X(UEL command) at the beginning and end of
	each job. (The order of these commands is critical. Refer to Structure
	of a Typical JobTable 4-1 for an example.)

The UEL Command (?%–12345X) has the same effect as the ? E command, and also enters PJL Mode of operation for printers that support PJL. The ? E command should be included to ensure backward compatibility (the UEL command is ignored if received by a printer that does not support PJL).
