I haven't tried this, but it's worth making this suggestion: Adjust the screen resolution to a greater value. That will make all the print smaller but it may also reveal the bottom of your Excel window. After you are done, you can reset the resolution. To do this, go to System Preferences > Displays and select the Display tab. Select the Scaled radio button and go from there.
