IPC: G06F3/12
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To prevent an overrun error and an underrun error. SOLUTION: A host 1 sends the image data of each page to a page printer 3 in each band unit and the page printer 3 writes each received band data in the receiving buffer within a DRAM 21 by a DMA and transmits each band data from the receiving buffer to image forming parts 13-19, 27. The host 1 obtains empty buffer capacity from the printer 3 immediately before transmits each band data and transmits the band data only when the printer 3 can receive the band data. In the printer 3, a CPU 23 permits the start of a transmission DMA by the data quantity calculated on the basis of a data receiving speed or a data transmission speed after receiving data are stored in the buffer in order not to generate an underrun error. The host 1 lowers the resolution of an image upon the reception of an error flag to re-send page data.
