ELECTRONIC MUSICAL INSTRUMENT WITH DIRECT PRINTER INTERFACE

Abstract

In an electronic musical instrument, a tone generator generates performance sounds of a music piece. A printer interface is provided for directly connecting a printer. An image data generation part generates image data of a musical score which corresponds to the music piece. A transmission part transmits the image data to the printer for allowing the printer to print the music score according to the transmitted image data. A print capability information acquisition part acquires print capability information representing a print capability of the connected printer. The image data generation part generates the image data in compliance with the acquired print capability information.
