Title: Noriyoshi Chiba: Innovator in Printing Technology
Introduction
Noriyoshi Chiba is a notable inventor based in Nagano-ken, Japan. He has made significant contributions to the field of printing technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and functionality of printing systems.
Latest Patents
Chiba's latest patents include a printing system that allows programs required for printer operation to be downloaded from a computer. This innovative system comprises a host computer and a printer that can process both first-class print requests, which include control programs and print data, and second-class print requests, which include only print data. The printer sends a control program ID as identification information of a control program stored inside the printer at that point in time. The printer control software installed on the host computer verifies whether the required control program is stored within the printer. If verified, a second-class print request is sent; if not, a first-class print request is sent. This system enables a printer to process print data in various languages and download control programs, resulting in a shorter average time required for printing.
Another significant patent is for a page printer and page print system. In this system, a host sends each page of image data to a page printer in band units. The page printer writes the received band data into a reception buffer in DRAM by DMA and transfers the band data from the reception buffer to an image formation section. The host checks the available buffer capacity from the printer before transmitting each band data and only sends the data when the printer can receive it. This method prevents underrun errors and ensures efficient data transfer.
