Setting options with devmode

I like to use PDF Creator from within my application to create PDF documents. I experimented with the Com interface but this really impractical to use, because the user can change settings and if he closes/restarts the app everything is out of control. The settings also inflicts when the user uses the printer for different applications since the settings are not explicitly coupled to a print job.

Is there a way to set options (especially the file name) with the devmode structure every printer exposes?
