hpStartMacro()

Begin a macro definition


Syntax

hpStartMacro(<nId>)


Parameters

<nId>
The ID number of the macro.


Returns

0
Successful.

-12
Wrong number of parameters passed.


Remarks

To create a printer macro, you would begin the macro definition by
calling hpStartMacro().  hpStartMacro() marks the macro as temporary
and assigns <nId> as its identifier.  All subsequent data is read and
stored as the definition of this macro until a stop macro definition or a
reset is received.  Stop macro definitions can be sent by using
hpEndMacro().

Note: Do not use any functions with a macro that would reset the printer,
i.e. hpConfig(), hpReset(), or hp Setup().


Support By

All HP Laser Printers except the original HP Laserjet
