Lanscape/ESC Codes

Hi, I'm trying to enable landscape printing, some specific financial program that uses PCL files and ESC codes. Printing on real HP/Lexmark/OKI printer works fine. I'm using  ESC Codes

27, 38, 108, 48, 79 ;Portrait
27, 38, 108, 49, 79 ;Landscape

I can print directly from my program to PCL and it will be Landscape. Why PDFCreator prints PDF (and PCL) always in Portrait? Is PDFCrator enable to read ESC Codes?
