Customized postscript driver options from pdfcreator

when I use pdfcreator to generate PDF files from Microsoft Word application, sometimes PDF file can only be generated correctly with the customized postscript driver option, e.g. postscript output quality option. However, when restarting the server, this advanced printer option is reset. So I would like to know how this option can be preset from driver level, e.g. customize the pdfcreat.ppd file. 

help me, guys. Thanks a lot,
