Title: Printer engine control system for page printer
Inventor: OKUBO HIROKI
IPC: G03G15/36
Filed: 1988-05-02
Abstract: PURPOSE:To shorten printing time per page and contrive a higher printing throughput, by starting paper feeding after video data for the first character in one page is formed in a bit-mapped memory, and starting a printing operation after video data for the one page is formed. CONSTITUTION:T1 is the video data forming time for the first character in one page, Tb is that for the one page, and Tf is the period of time required for feeding a paper. Paper feeding is started at the time t1 when the video data for the first character is formed. When Tb>Tf, the period of time before the start of printing is Tb because the printing is started at the time t2 when the video data for the one page is completely formed, so that the printing time for the page can be shortened by the paper feeding time Tf. When Tb>Tf, the period of time before the start of printing is T1+Tf because the printing is started at the time t3 when the paper feeding is finished, so that the printing time for the page can be shortened by Tb-T1.
