HP 5961-0509 manual Job Separation Command, ? & l 1 T, Separation will be performed

Job Separation Command

Job separation provides a means of identifying one print job from others in the printer’s output tray. It usually does this by physically offsetting one print job from the next.

The Job Separation command toggles the printer’s separation mechanism. This command must be sent between each job to enable the separation mechanism.

? & l 1 T

	HP recommends that the Job Separation command be included at the
	end of each job, just before the Printer Reset command. HP also
	recommends that this command be included in the programs even
	though printers with job separation are not currently being used. This
	ensures that if a printer with job separation is eventually added, job
	separation will be performed.
	If this command is received by a printer which does not have job
	separation, the command is ignored.
Note	It is possible to perform job offset in printers which do not have a
	mechanical offset mechanism but have dual paper trays. In dual bin
	printers, job offset can be performed by placing colored paper in the
	second tray and using Paper Source command to select the tray to
	feed a blank sheet of colored paper at the end of a job. This method
	should only be used in special cases where the end user can control
	its use, for example, the program should only be available for a dual
	bin printer which can always contain colored paper in one tray.
