No not using that method my guess is your going to have to pull printer
information and write it back using an API Call
try here for a nice list of API calls

Mike,

Have you tried using SENDKEYS to specify settings for your printer?

These work to alter the portrait/landscape simplex/duplex settings on my
LaserJet5SI.

%FU is the same as Alt-F (File) Setup
In the first example, %O is Alt-O (Options) then you just add whatever
letters you'd have to type to do the job manually.

Hope this helps

Pete
