Defining a Macro
To define a macro you must first assign an ID number to it, then send to the printer a Start Macro Definition
command, the macro definition itself (consisting of a sequence of PCL commands) and finally an End Macro
Definition command.

Macro ID
Esc&f#Y (27)(38)(102)#(89)
<1Bh><26h><66h>#<59h>
This command assigns an identity number to a macro that is to be downloaded, or references an existing
macro in the printer's memory.
# is the ID number of a macro. The ID number must be in the range 0-32767.
If you specify the ID number of an existing macro and then download a new macro definition to the printer,
the new macro will overwrite the existing macro.
