Printing the score in a much bigger size

Hi experts

I need to print a score in a much bigger size, including staff, notes and text.
Zooming +/ - on screen is very easy, but can't find out to print in a much bigger size.

I need to print in a size where there is only one or two measure across an A4 paper portrait/ landscape.
I tried if it was possible to export a PDF and do the printing from adobe program, that didn´t work.

Appreciate very much if anyone can tell me how do I scale the score to do this ?
