My PhD thesis needs to be in A5 format.
During the review process my professor would ideally have the A5 document pages printed on A4 sized paper.
I know that I could just generate the content in A5 and then in the printer settings choose to have it printed on A4 pages. However if there is an easy option to change the outer measurements of the pages from A5 to A4 and later back to A5 (for the final print) this would be preferable as it does not leave the page resizing in the professor's hand.
So I would like to ask if there is a possibility to do something like this with a single package or command in the preambel?
