Host computer connectable to a recording apparatus through signal supply means

摘要

An ink-jet recording apparatus, having a printer that performs recording by jetting ink from a recording head according to recording data, comprises a plurality of signal lines that supply the recording data to the printer and are connected to a host for controlling the printer, and an information transfer unit for transferring the information to the host. Herein, the plurality of signal lines include at least a first signal line for transferring recording data and commands from the host to the printer, and a second signal line for transferring printer information to the host. Thus, the ink-jet recording apparatus offers excellent cost-efficiency, system reliability and operability.
