If you are talking about the field maps, they are located in the "maps" folder of the installation directory for Aces High II (default location C:\Program Files\HTC\Aces High II\maps). They are ordinary bitmaps you can load into MSPaint (or any other paint program) and print out.
If you are talking about the terrain maps, they are not available as bitmaps. You would have to take a screen shot (ALT-S to save in Aces High II installation folder, or ALT-PRINT SCRN to paste to a paint program) and then print them from a paint program.
