'G' and other letters are printed instead of noteheads and music symbols.
If the printout of your score fails to show music symbols and instead shows letters (such as a 'G' instead of a notehead), the problem may be due to too many fonts in your Windows/Fonts folder (please see the following page for more information http://www.online-tech-tips.com/windows-7/windows-7-fonts/)
When you encounter this problem with Notation Composer/Musician, the solution is to temporarily remove fonts from your Windows font directory. The steps are:
1. First, exit Notation Composer.
2. Right-click the Windows Start (globe) button at the left bottom corner of your screen. A small menu will be displayed.
3. In that menu, choose 'Open Windows Explorer'.
4. In Windows Explorer go to c:\Windows.
5. In the list of sub-directories of Windows, right-click the "Fonts" directory. A menu of options will be displayed.
6. In the menu of options for the Fonts directory, choose Properties. It will display the number of "files" in the Font directory. That is the number of fonts. Exit the Font Properties by clicking Cancel.
7. Create a sub-directory of the Fonts directory, named something like "InactiveFonts". Do that by selecting the Fonts directory in Windows Explorer, and then choose New Folder in the list of options at the top of the menu, or in earlier versions of Windows, choose New Folder from the File menu.
8. In the left panel of Windows Explorer, open navigate to the newly created Windows / Font / InactiveFonts directory.
9. In the right panel, navigate to the Windows / Fonts directory and double-click Fonts. A list of the fonts will be displayed.
10. Identify fonts you don't need, and drag them from the list on the right panel (for Windows / Fonts files) and drop them into the Windows / Fonts / Inactive Fonts directory in the left panel.
11. Run Notation Composer again the try printing. If the problem persists, then move some more fonts to the InactiveFonts folder.
