pandoc iz_test.html -s -o iz_final.pdf

I noticed the default setting is that the pdf prints to portrait but I'd like my pdf output to print as landscape.

Reviewed the options setting and I've saved a new default.tex file in C:\Users\myusername\AppData\Roaming\pandoc

Any suggestions on how I should modify my default.tex so my output prints in landscape?  My output pdf still prints in pdf.

Thank you.
