Why won't draftsite print 22" x 34" and how do I fix it?

I can't get Draftsite to print a 22" x 34" drawing. It tries to print the drawing as 11" x 17" on the large paper. I need some ideas on how to fix this. Thanks for all your help.

It is also printing gray scale even though I have it set to monochrome.
