Latest Patents

Onuma holds a patent for a "Page printer and page print system." This invention involves a host that 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 using DMA and transfers the band data to an image formation section. The host checks the available buffer capacity from the printer before transmitting each band data, ensuring that data is sent only when the printer is ready to receive it. This system is designed to prevent underrun errors, with a CPU that manages data transfer based on calculated reception speeds. If an underrun error occurs, the CPU sets an error flag, prompting the host to drop image resolution and resend the page data.
