Why does my pdf print at 49% scale when I want to print my A0 to a A2?

Why does my pdf print at 49% scale when I want to print my A0 to a A2? When I choose custom scale at 50% it prints it A4 size on an A2, alternatively, leaving the paper it prints it at full size on an A2

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.

Please show a screen shot of the Print Dialog when the print is at 49% scale.

Also please say whether the preview in the Print Dialog is right for what comes on paper.
