Reduce Page Margins as well as Print Margins when printing two pages in one sheet

Hello!

I have a pdf document, and I want to print two pages in one sheet, which is very simple. The challenge is that when I do that, the text size is very small and is difficult to comprehend. I want:

1. to reduce the page margins that are left blank all around the text; and

2. to reduce the print margins (set the print margins, rather, to my convinence) so that the space between two pages while printing can be reduced.

My sole motive is to print two pages in one sheet along with reducing the blanks or the whites to the minimum possible extent.

Thanks in advance.

Regards
