Print from chrome, automatically, using OS printer menu settings

I have an extension running on Chrome with kiosk-printing on. I'm on OS X 10.6.8.

I want it to print a page via the extension, without any dialog.

This works fine with just print(), but chrome prints using settings other than my required preset (page size etc')

How can I make chrome use my required preset?

I've tried the following:

Looking into where the presets and standard settings are saved according to this http://hints.macworld.com/article.php?story=20100125135830153. It seems that chrome doesn't use these settings.
Using the CUPS UI to change the standard preset, but it seems chrome doesn't use these settings either.
Using the disable-print-preview flag, but then the system dialog appears and I lose kiosk printing.

Solution

I couldn't find a built in solution, ended up using an applescript to click the print button of the dialog.
