Printing a legal size PDF - cuts off text on right margin

I have a one page legal size PDF and when I print in landscape layout, a small portion of text in the right margin is getting cut off. In the print dialogue box I have selected Actual Size, landscape layout, and above the print preview image it shows that the paper size is 14 x 8.5. However looking at the print preview image, there is a slight grayed out area on the right edge of the paper, showing that the text is getting cut off. I am stumped as to why this is happening. Help, please!
