Jonathan,
Just let me put in my two cents here.
Acrobat Reader goes through frequent updates. Many clients have it set for
auto update, so you have little control of their version.
If you are trying to do something that Leonard says is no longer supported,
you could save yourself a lot of time by trying to figure out another way
around the problem. I have used in the past many "unsupported" command line
switches in AR and always been stung later with a version change that no
longer supports that particular switch. The silent print option is one that
I think everyone would like to have, but for reasons explained by Leonard in
a post in the last month, Adobe no longer supports this (security risk?).
I fail to understand this reasoning by Adobe since the possibility of a
malicious bit of code printing reams of paper is not really much of a
"threat" in my book. But I am not Adobe and they may have many other
considerations that I am not aware of. I'm just happy they offer a free
Adobe Reader which makes my programming life easier in many other ways.
Personally, I went to using Ghostscript (free) that does officially support
its command line switches and where you can print silently to any printer.
So far, this has worked out well for my users who only have the extra hassle
of installing Ghostscript one time.

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.
