Hi Jean,
I'm not sure which version of Windows you have, but assuming it is Windows XP:
Right click on the file you wish to open (eg music.jpg)
Select "Open with"
You should then see a list of suitable image viewing programs that are installed on your computer. These will probably include "Windows Picture and Fax Viewer", "Microsoft Photo Editor" and "Paint".
If you now left click on any of the listed programs it should then open and display your image of the sheet music.
From there you should be able to print it by either selecting print from the file menu or clicking on the printer icon.
Cheers
Len C.
