Abstract: The present invention provides a technique that simplifies operations for making appropriate print settings. Accordingly, a terminal apparatus serving as an information processing apparatus according to the present invention acquires, from a printing apparatus, information indicating the sheet type and size of the sheets set in each paper feed tray. Then, the terminal apparatus determines whether the acquired information includes a sheet type that matches a sheet type suitable for an attribute of information selected by a user as a print target. If it is determined that the information includes a sheet type that matches the suitable sheet type, the terminal apparatus generates print data including information designating a paper feed tray containing sheets of the matching sheet type, and transmits the generated print data to the printing apparatus.

Abstract: A driver circuit for driving actuating elements for printing, has a switch for coupling a common drive signal to provide element drive pulses to drive each actuating element according to a print signal. A timing control circuit controls the switch during sloped transitions of the common drive signal, to trim an amplitude of the actuating element drive pulses according to a common offset configurable for at least two of the actuating elements in common, and according to an element specific offset, configurable for each of the actuating elements. The offsets can be dynamic or static, and some parts of the timing can be implemented in analog form. This enables more types of errors to be compensated, and can enable the element specific offset to be implemented with simpler circuitry with less heat dissipation or less space or needing less precision and thus less cost.
