DOUBLE-SIDED PRINTING SYSTEM AND CONTROL METHOD THEREFOR

摘要

The invention provides a double-sided printing system and a control method thereof. The double-sided printing system comprises: a host which comprises a first generation unit for generating first printing data to be printed on a first side of a medium, and a second generation unit for generating second printing data to be printed on a second side of the medium; and a printer which comprises a controller, a first data buffer area for receiving and caching the first printing data, a second data buffer area for receiving and caching the second printing data, a first print head for printing the first printing data on the first side of the medium, and a second print head for printing the second printing data on the second side of the medium. By means of the double-sided printing system, the data processing load of the controller of the printer can be decreased; furthermore, as the double-sided printing is performed by independent generation units and interfaces, it enables double-sided printing without changing the application programs of a single-sided printing system, thus further conveniently converting a single-sided printing system to be a double-sided printing system.
