receiving options with pycups

Hi people! I have successfully created a Connection and printed a page. What I figure out, that if I print a "file" (a TIFF Page), the output is totally different, as if I would manually print the page from a viewer GUI app. How do I get the available "options" of a printer through pycups, which I want to use for printing. Let us say, the system predefined standard printer. For a response I would kindly thank you Tamer
