how to shrink pdf files for printing

Hello all.

I have several scanned documents in my google drive and I am trying to print them on real size (passports, identifications etc.). But...whenever I try to print them they fill the complete printing page and I haven't found a way of shrinking the picture on my MacBook Pro Mojave 10.14.6.

I have done the shrinking with adobe on a windows computer but I would really like to keep using my Mac ....and not having to switch computer every time I have to print.

Is there a solution for this problem with the stock apps that come with the MacBook Pro? Or is there a free third party app for my Mac that can do the trick?

regards
