Title: System and method for controlling printing
Inventor: YAGI MASAYA
IPC: G06F3/12
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To detect a printing data break owing to a transfer error or the like through the use of a printer controller by transferring data by a transfer system proper to a data kind and adopting a result obtained by synchronizing and synthesizing respective kinds of data as printing data. SOLUTION: A transfer permission from a route is made for a printer. Then the kind of data transfer is judged, character graphic data are received when it is asynchronous transfer and received character graphic data is temporarily stored in a memory. Besides, character graphic data are rasterized in the development area of a memory by referring to font data or the like. In the meantime, when the transfer is the isochronous one, image data are received and temporarily stored in the memory. Then rasterized character graphic bit map is synthesized with an image, printing data are transmitted to a printer engine and a printing processing is executed. Thus, asynchronous transfer and isochronous transfer are maximally utilized so that printing data are efficiently transferred.
