is there a ways to center your layout to page when printing?
Not as an explicit option.
Things that may help.
Use the view menu to show page breaks.
In layout setup, you can specify margins.
For fields and layout text that needs to be centered horizontally on the page as you might need in the header, select center justification, then put the left hand edge of the object on the left hand edge of the layout and pull the right hand resize handles to the right until it touches the vertical page break line.
I haven't tested much, but
Then centered on any paper size.
