Sam,
PS and PCL are languages printer hardware understands.The job of the driver
is to convert whatever info is present from the screen device context to
printer device context.
The print driver would actually play the EMF which contains nothing but GDI
calls like LineTo,MoveTo and so on. So now the Driver inturn calls the GDI
to do the rendering on to the Printer DC.The print engine would take care of
the PCL/PS comand relevant to each GDI call.
