Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To shorten a time to an output start with a small memory by reducing preliminary plotting bands in a printer apparatus carrying out a band process. SOLUTION: An editing part 12 analyzes printing data received from a host apparatus 2 and generates a plotting time 22 for each band. A judging part 13 judges on the basis of the plotting time 22 of each band and a video output time of one band which of preliminary plotting and real-time plotting is to be carried out. Since a CPU is unoccupied during the video output of a preliminary plotting band, the time is allotted to a real-time plotting time for a next band. After a counter is cleared to 0 when the judgement is started, the plotting time 22 of the band is obtained, and set to the preliminary plotting band if the plotting time 22 is not smaller than the video output time of one band *(counter value +1). The counter value is incremented. Otherwise, the plotting time is set to the real-time plotting band, and the counter value is cleared to 0.  The process is carried out for each band of the subject page.
