Abstract
A print head for which the number of bits can be set to a predetermined value when a plurality of driver ICs are connected. Data input through a data input pin is passed through an internal shift register and output through a data output pin. The data output pin of one driver IC is connected to a data input pin of another, thereby providing any desired number of shift register bits. Each driver IC has additional data output pins and can output intermediate data through one of the data output pins. Therefore, the additional data output pins can be used to change the number of significant bits of the driver IC. Consequently, when the driver ICs are connected to each other, the number of shift register bits can be adjusted.
