A device to select and drive recording elements included in a print head that prints images, for example, a nozzle. The device includes an encoder to encode address data, a decoder to decode the encoded address data to restore original address data, an address data bus to connect the encoder with the decoder to transfer the encoded address data to the decoder, a driver to drive the recording elements using the primitive data and the decoded address data, and a primitive data bus to transfer the primitive data to the driver. Accordingly, when the recording elements included in the print head are driven using the primitive data and the address data, the address data can be encoded so that neighboring recording elements share the address data bus to reduce the number of address data bus lines and a size of a print head chip.
A device to drive recording elements included in a print head and divided into a plurality of groups using primitive data to select groups to be driven from among the plurality of groups, and address data to select recording elements to be driven from among the recording elements belonging to the selected groups, the device comprising:
A device to drive nozzle groups in a print head, the device comprising:
An image forming apparatus, comprising:
A method of driving a print head having a plurality of nozzle groups with N nozzles in each group, the method comprising:
