Watermark in Postscript Driver

Hi!

I want to put watermark feature in Postcript driver using plug-ins.
What I have done is writing the watermark text on Printer DC at Document
event end page.
This way it draws text but only problem is text is over the page and the
data on page is hidden under watermark. Where as I want it to be meged with
data on page so that both are visible.Basicaly Transparent text.

I believe some ROP code may solve the problem but in case of PS no ROP code
seems to work.

The another way of writing watermark is the way given in DDK example using
PDL but in that case how do I send font info when the selected font for
watermark text is not device font.

Thanks
Naveen

Normally the watermark is possible with the PostScript language. Look at
the reference, what to do.

Hi!
Thanks for your response.
I know I can write Postscript procedeure to draw watermark, but my problem
is that user will select some font from driver UI to draw watermark and if
the selected font is not device font then I need to embed that font in spool
so that printer can draw watermark in that font.
How do I send font to the printer?
