With the demo version you cannot save files and you can only print 1 line,
one time. Once you print one line, one time you cannot print at all. 
Nevertheless, there is a print preview button which will show you exactly 
how it's going to look if you were to print it out.

Also, you cannot Export your score in other formats, which is a feature 
that only the Licensed version of MW Maestro offers.
