GIMP :: Print / Canvas Size - Picture Cut Off (4x6 Paper)

I used scale image to make a 2.314" x 3" image to print so it'll fit in a frame that I have for that same size. When I print it out the size looks great but it's over on the edge of the 4x6 paper and most of the picture is cut off. I tried, I should use print size and not canvas size but when I change the print size to 4x6 it also changes my canvas size back to 4x6. I still have my original so I can do this again but what I want is a 2.314"x3" image to print out on my 4x6 glossy paper.
