sheet templates?

How do I change the default template sheet sizes if I was wanting to print to an 11x17 instead? Have searched will no success.

Also, when trying to print, is there a save option once you have dialed in the setting as you want all prints to appear? Every project I try to print I have to reset all settings...not sure if I missed something or if this just simply isn't a well needed option?

Any information would be appreciated.

Thanks.
