Please verify you have the font "spw.ttf" installed in Windows.  (To check 
which fonts you have installed, open Control Panel.) 

Make sure your printer is set up correctly.  (The Music Writer section of 
the Discovering Music manual has further instructions regarding printer 
setup.) 

Note: Before entering the Discovering Music program, you may wish to 
      test your printer with Windows Notepad to confirm your printer 
      is functioning correctly.
