发明名称 Processing blank data-lines of print data
摘要 A system and method are provided for a printer which divides raw bands of print data corresponding to a page to be printed into a plurality of sub-bands. By generating sub-bands of print data for each page, a segmented page frame buffer can be used to store the print data non-contiguously in the memory segments of the buffer so that the memory may be used more efficiently. Also, a compressed data line representative of blank data is stored in the memory for eliminating redundant operations of processing and storing blank data lines (data lines containing no data). As a result, every time a blank data line is detected, the compressed blank data line stored in the memory can be pointed to and the performance of the printer is enhanced by reducing the printing time.
