Macro Creation - HP PCL 5 Reference Manual

Macro Creation

Designate a unique identification (ID) number prior to the definition
of a macro using the Macro ID command. This number is assigned to
the macro. If a macro is already associated with this ID number, the
previously existing macro is deleted from user memory during the
definition of the new macro. Subsequent macro operations are
accomplished using the macro ID number.
A macro is created in the printer in several steps. First, the start
macro command is sent to the printer to indicate the start of a macro
definition. Next, the printer commands, control codes, and data that
constitute the macro are sent to the printer, in the intended order of
their execution. Finally, the End Macro command is sent to the printer
to indicate the end of the macro definition
