Hello
Bullzip is the best PDF printer that I know, but there is at the moment one thing that I miss.
If I add a PDF file as a watermark, this watermark does get "converted" into an ugly (resized) image, in stead of adding the PDF file as a "searchable PDF watermark".
As you are already using GPL software for you product, could you try to have a look at this: http://www.accesspdf.com/pdftk/
pdftk is able to do this perfectly - please try - follow this example:
pdftk in.pdf background background.pdf output out.pdf
This will make it look perfectly like it was created at one single point.
There could also be other features in pdftk that Bullzip could make use of.
