If the only thing you change is the print resolution (dpi, ppi, or pixels/inch), then the printed image will get smaller. If you also increase the pixel dimensions to compensate, which I believe PS does by default, then your image will still print the same size, but there will probably be noticeable artifacts from the resample.
