http://www.zeon.com.tw/pdfdrive/pdfdriverapi.pdf
Armed with this document, you can control the PDF Driver behavior programatically.

--  For example, you can:
* hide the "Save As" dialog box; 
* control the compression; 
* add Watermark to each page; 
* embed fonts;
* or even hide specified words.
* inlcude custom Document Info.

==== 7. Known Problems

--Printing problem
Use Acrobat Reader 4.05 or above for the printing. PDF Driver produces PDF spec. 1.3 document. You can not "COPY" PDF file to the printer, unless the printer also supports PDF spec. 1.3 

--Symbol(special characters) looks different
When creating original document, please make sure NOT to use "Device Fonts". Device fonts are available only on a specific device. Therefore, they are not suitable for PDF generation. Always choose TrueType fonts rather than Device fonts. For example: Instead of using the "ZapfDingBats" -- a Device font, you should use "Symbol"--TrueType font.
   
--(MS Office) Sometimes graphics and text data are wrongly overlaped: 
This is a known application problem - the sequence of objects are wrongly given by MS Office software. Try to use a newer version of MS Office.

--(MS Office) Outline effect of characters are wrong:
Because MS Office software send wrong character codes to DocuCom PDF Driver. Therefor the display becomes un-readble. Use a newer version of Windows. (only under 95/98, NT/2000 have no such problem)

-- Transparent Color: Usually, Printer Driver cannot handle transparent color correctly, such as the transparent color defined for the drawing objects of MS office, or the transparent color defined for GIF image to be displayed by Web browser. All those transparent colors are simply ignored.

-- Windows Pattern: Certain Windows GDI defined patterns are not supported correctly. Should be fixed in next release.

-- PDF Form: When printing a PDF document with filled-in forms (using Acrobat) to PDF Driver, characters in the form input field cannot be reproduced by PDF Driver. It seems Acrobat passes strange fontname in above case. Should be fixed in next release.

Professional DTP publishing software:

--You may encount problems using PageMaker(TM) while printing complex graphics and text. Use DocuMaker instead.

--PDF Driver may fail when you print very large and/or complex CorelDraw(TM) files - use DocuMaker instead.
