How do I print 1:1 on paper for actual size?

Hello --

I had made a test drawing in inches, added the dimensions, and printed to letter size paper. I measured the shapes drawn and found they were spot on against a ruler. This is what I needed. Most of the things I will draw are small and can be printed on letter size paper, and need them scale 1:1 on paper. Plan is to glue paper print to plywood and cut along the line of drawing, simply put.

However, I lost the settings for this somewhere and cannot recover to where I left off. Drawings are not printing 1:1 to paper, in spite of tweaking what I think are the obvious sheet and print properties.

Can someone assist me in getting set up for drawing small parts and printing them to actual size on 8.5 x 11" paper? I feel kinda dumb for getting it right the first time, and now not getting it the second time...

Thank you,

Mark
