Resample - Changing the pixel dimensions of a bitmap image. When you decrease the number of pixels in the image, you are downsampling, which results in a loss of image data and a blurrier image.
Resample - Resampling an image changes its resolution through interpolation, making calculations using already known values.
Resample. To change the size or resolution of an image. Resampling down discards pixel information in an image; resampling up adds pixel information through interpolation. See also interpolation.

I'll need to resample the image down to a smaller resolution in order to achieve this size print when I assign 300 ppi as the document's printing resolution. I'll also need to digitally crop the image from the 35mm film's 8X12 native ratio to 8X10.
Genuine Fractals is a lot better than a Photoshop resample for lines, although when used for rasterized text (not shown here) it really does not work anywhere near as well as it could.

I figure that I want print resolution at about 300 pixels per inch in PS, and therefore, unless I resample up, I am restricted in the size of photo by the number of my original pixels.
Turn off the Resample option and then change the DPI to 300.
It is just a number, that has nothing to do with resolution:
e.g.:
An image of 1200 pixels wide will be 4 inches at 300 dpi or 8 inches at 150 dpi.
Image size again, untick the Constrain proportions box (you'll have to tick the Resample Image box first if you're using Elements - choose the Bicubic Smoother option) and change first the image resolution and then the pixel dimensions to match your ...

Change the document size unit to Percent.
In the Document Size section of the, enter 110 for the width of the document.
Scale Styles: Check the box.
