RE: Implementing watermarks in the print processor

Hi!
It is not advisable to modify spoolers EMF as the format of spool file may
change in later releases.
I believe you were trying to draw from DrvDocumentEvent EndPage and End Page
event does not come in banding drivers. Typicaly color raster drivers are
banding drivers. In all other cases you will get DocumentEvent endPage and
you can draw watermark on Printer DC from there.
Other aproach may be to draw watermark from Printprocessor on printer DC but
in that case watermark will always be underpage.
If you are working on PS driver then you can inject PDL to get watermark see
watermark sample in DDK.

Hope this helps
