Music works prints music using a Hewlett Packard laserjet 5100tn. This printer prints up to A3 size at 1200DPI producing the highest quality printed music. Single sided, double sided and bookletting can all be easily achieved. I will be happy to send you examples of my work. Just email me with your requirements and address.
A3 (297mm x 420mm) is a common size for medium or large orchestra scores for conductors. B4 (250mm x 353mm or B4 JIS 257mm x 364mm) are good sizes for players' parts. A4 is also useful for players' parts but the music is smaller than it would be on B4 and there may be more frequent page turns. Wiro binding ensures the music opens flat.
