Usage of applescript dictionary from ""

Good day everyone,

Apple’s own printer proxy application, which bundle id is “”, has the AppleScript abilities.
This app is found in Printers folder of local user’s Library.

Does any one know how to get its dictionary statements work in applescript?
There is a suite called “Printer Proxy Suite” with 3 custom classes in it and their properties. And thats it.

Here they are:

Thanks in advance!

To be more precise.
I tried all the possible AppleScript expressions I know, wrapped into this:

tell application id ""
-- property request	
end tell

Nothing seem to work. I always get the “error number -1728 from *** of «class prnt»”

P.S. What I’m trying to do is to have some feedback from Lisanet’s PDFwriter installed on my mac.
