My printer supports 1200x600 non-square resolution. I need put halftone threshold array in postscript file dynamically. Right now, I can put threshold array in postscript file, then add some code in my postscript file to load the threshold data and use ghostscript to process it. 

I hope somebody could tell how to use PPD to load the halftone threshold data so that when I print postscript file, the halftone data will automatically insert to the postscript file. 

Thanks a lot.
