Labels do not transfer to print screen at correct size.
Label borders and text inside do not transfer correctly to print screen.

Labels should retain their approximate size when printing, so long as:
1. The map scale in the main map window matches the map scale in the Print window. (You can type any scale you wish in either window.)
2. In Layer Size/Visibility, the sizing slider is in the center position.
3. In Layer Size/Visibility, the option to Conform layer size to Map Scale is turned off.
4. Also the Print window, the sizing slider is in the center position and Conform layer size to map scale is turned off.
This should produce the expected results in most cases. However, due to the method Windows uses to render fonts on the screen vs. on a printer, the label may need to be slightly oversized to avoid text wrapping unexpectedly.
