Hi Leonard
Thank you for your reply.
I am currently using Adobe Acrobat Reader 7.0.9; So I guess it should work
fine right?
Which method are you talking about exactly? this.print()?
I created the javascript code based the javascript API from adobe version
8.1. April 2007; And everything I used can be found in that API.
