What kinds of music can be printed?
Virtually anything, from rock to avant garde music and from guitar tab to full orchestral scores. For practical purposes the most suitable scores are shorter ones such as songs, keyboard music, solo pieces and parts, because they don’t need to be bound or double-sided. In the next few years printers which print double-sided and bind will become widespread (they are already starting to be used by bookstores to print books on demand).
