How does one change default options in CUPS I want to change default print settings in CUPS. 

I'm mass printing PDF's through Finder and it won't use my preset in the printer options menu so I'm fiddling around in CUPS to see if that works. I want to change the settings as shown below, but I can't find out how?

Essentially I'm trying to print all pdf's with Scale to fit enabled, if there is some other way I should be doing this. I'd like the heads up :)
Since I essentially wanted to print all pdf's with Scale to fit enabled. This small command worked.

lpoptions -o fit-to-page
