Title: Image recording apparatus and controlling method therefor
Inventor: KURONUMA AKIRA
IPC: B41J2/01
Filed: 2001-04-02
Abstract: PROBLEM TO BE SOLVED: To provide an image recording apparatus capable of shortening the DMA processing time used for processing recording data, and a controlling method therefor. SOLUTION: The processing time is shortened by cutting back the number of vertical-lateral conversion processes of data, executed at the time of transmitting recording data to a recording head. That is, at the time of transferring a predetermined number of data out of the recording data from a receiving buffer to a work buffer per one raster, the rear end N with data to be recorded included is detected so that the maximum value thereof Nmax is calculated. The processing time is shortened by cutting back the number of unnecessary vertical-lateral conversion processes by limiting the number of the vertical-lateral conversion process to Nmax at the time of subsequently transferring the recording data stored in the work buffer to the printing buffer after the vertical-lateral conversion processes.
