HP 5961-0509 manual Macro Invocation, 12-4Macros

Macros occupy a portion of user memory. The number of macros that can be stored simultaneously in user memory is limited only by the amount of available user memory.

Macro Invocation

	There are three ways to invoke a macro: execute, call, and overlay,
	using the Macro Control command.
	When a macro is executed, it begins performing its commands using
	the current modified print environment. Changes made to feature
	settings during macro execution are recorded in the modified print
	environment; these changes are retained upon completion of the
	macro execution.
	When a macro is called, it begins performing its commands using the
	current modified print environment. Before the macro is performed,
	the current modified print environment is saved. Changes made to
	feature settings during a macro call are recorded in the modified
	print environment; however, these changes are not retained upon
	completion of the macro call. The modified print environment that
	existed prior to the macro call is restored.
	When a macro is enabled for automatic overlay, its execution is
	the final operation each time a page is printed. Before the macro
	is performed, the current modified print environment is saved and
	replaced with the overlay environment. The overlay environment
	is a combination of the user default and the current modified print
	environments. Changes, made to feature settings during macro
	overlay, are recorded in the modified print environment; however,
	these changes are not retained upon completion of the macro overlay.
	The modified print environment that existed prior to the macro overlay
	is restored.
Note	HP-GL/2 commands are not supported within macros on all
	HP LaserJet printers. Refer to the “PCL Feature Support Matrix”
	in Chapter 1 of the PCL 5 Comparison Guide for specifics.
