Hi Hector:

VFP does not support all data types, and for some ActiveX you may need to convert from one type of data into another.
The VFP2C32 library allows working with C++ structures and pointers, to interface with VFP data types.
I didn't use it yet, but you can find it here:

Respecting Fiscal Printers, you may subscribe to the GUFA email List (Grupo Usuarios FoxPro Argentina). As for what I see, they talk almost exclusively about fiscal related topics (VFP programming and hardware/drivers related) all the time, and there are some developers with even electronic knowledge that may give you sam advice too.

You can subscribe to GUFA List in http://www.mug-it.org.ar/, under Listas/Suscripción menu, selecting GUFA list.


Best Regards.-
