Prints are smaller than they should be according to the image's PPI value
I brought in a jpeg image and wanted to scale it to a certain size to print. I watched the scale dialog box until I got it the size I wanted and hit "scale". When I went to print at 100% is was significantly smaller than my desired size (about a half inch on the X and Y). I had to keep scaling up the image, and go to print preview, scale the US Paper to the correct size then measure the image on the screen until I got it correct. It then printed the correct size.
