Patent ID: 7463372

Claim:
A recording system comprising: a host device, a communication line, and a recording apparatus connected to the host device via the communication line, wherein the host device is operable to transmit image data to the recording apparatus and the recording apparatus records an image onto a recording medium based on the image data transmitted from the host device, the recording apparatus recording the image with an ink-jet recording head moved by moving a carriage; the host device comprising: a determining unit configured to determine an encoding method to encode the image data for a data compression rate that is a lowest compression rate among data compression rates in time of not over a time for one recording scan of the carriage based on at least one of a data communication rate of the communication line and a processing rate of the recording apparatus; an encoding unit encoding the image data based on the encoding method determined by the determining unit; and a transmitting unit transmitting the image data encoded by the encoding unit to the recording apparatus via the communication line; the recording apparatus comprising: a receiving unit receiving the encoded image data from the host device via the communication line; a decoding unit decoding the encoded image data received by the receiving unit; and a recording unit recording the image based on the image data decoded by the decoding unit.
