Uncle...  I've watched videos and searched the commands trying to solve this problem. It's likely simple but has me stumped. 
An uncropped camera pixel aspect ratio is 3:2 (1.50/.67), 4:3 (1.33/.75), or 16:9 (1.78/.56).
Typical home printer paper is 4x6 (.67), 5x7 (.71), 8.5x11 (.77), 11x17 (.65), 13x19 (.68), and 17x22 (.77). 
For example, I want to retain the entire pixel size of a 3:2 landscape image and fit it onto the 8.5x11 paper, with no enlargement, i.e., clipping of the long edge. I can't find that setting(s).  

Please help.
