The present invention discloses a data transfer method wherein data is broken up into N datablocks (where the number N is a natural number) for transfer from a first node to a second node on a bus system each of whose nodes is assigned a node identifier, wherein the data transfer method comprises, prior to transfer of the datablock, a step in which a control node (1) issues to the second node a datablock reception instruction containing therein a node identifier of the first node and (2) issues to the first node a datablock transmission instruction containing therein a node identifier of the second node, thereafter, a step in which the datablock transfer from the first node to the second node is executed, after the datablock transfer is completed, a step in which the first node notifies the control node of a result of execution of the datablock transfer processing, and a step in which the second node notifies the control node of a result of execution of reception processing on the datablock.

Data transfer method, data transfer system, data transfer controller, and program recording medium

A printing apparatus having a plurality of printing wires or hammers. The printing apparatus has a main drive driven continuously at a resonance frequency so as to supply energy to the plurality of printing wires or hammers, a plurality of selective drives corresponding to the plurality of printing wires or hammers, selectively energized by printing signals so as to transmit the driving energy to the printing wires or hammers. The printer head assembly can be extremely small sized and operate with low energy.
