Abstract: A printing system capable of dynamically changing a billing method for an ink usage amount for other than printing is provided. The printing system including a server and a device includes an accepting unit to accept printing instructions, a printing unit to perform printing by an inkjet printing method, a counting unit to count an ink amount used for printing for each user, a counting unit to count an ink amount used for other than printing, a counting unit to count the number of printed sheets for each user, a setting unit to set a billing method to one of a billing method based on the unit price for the number of printed sheets and a billing method based on the unit price for an ink amount, and a billing unit to perform a billing processing based on at least one of counting results obtained by the counting units.

Abstract: A recording method includes recording while performing a scan by a carriage mounted with a recording head that discharges ink, changing postures of the carriage at each of a plurality of positions in a scanning direction such that changes in the postures are reduced at the plurality of positions.

Abstract: A direct memory access (DMA) transfer apparatus configured to sequentially read, into a register, at least one transfer setting value for data transfer stored in a memory and to perform DMA transfer processing based on the read transfer setting value includes a unit configured to receive a No Operation (NOP) designation for designating no performance of DMA transfer as the transfer setting value, and a unit configured to generate, if the NOP designation has been performed with the transfer setting value read into the register, an NOP interrupt signal to end transfer processing without performing the DMA transfer.

Abstract: A printing apparatus for effecting printing using a recording head mounted thereto includes a communicating section for communication with an information processing apparatus; a control section for determining a kind of device among a plurality of kinds in response to a predetermined operation for setting the kind of the printing apparatus, and operable for the kind thus determined; a discrimination section for discriminating whether the kind of device is determined or not; and a communication control section for controlling communication with the information processing apparatus by the communicating section in accordance with a result of discrimination of the discrimination section.
