There is no sure way of figuring this out from the plug-in layer. It really
depends on how the app chooses to implement print-to-file. You might be
figure this out by looking at the DOCINFO structure that is passed to GDI in
its StartDoc call. You can access this structure by implementing the
DrvDocumentEvent hook in your plug-in and catching the
DOCUMENTEVENT_STARTDOCPRE event. If the printer itself has been installed on
the FILE: port, then you can detect this by examining the
DOCEVENT_CREATEDCPRE structure passed to you at DOCUMENTEVENT_CREATEDCPRE.

Thanks for your advice. I'll give it a shot.

Firstly, this hook does not exist on W2K. It exists only on XP. But since XP
Unidrv and PScript were backported to W2K in SP3, you should be able to
implement this hook on W2K SP3. Second, this function is part of the UI
dll...so you cannot implement it in a rendering dll.
