    摘要： A method to connect a wide sized document scanner to a laser printer engine for copying with size reduction enables the output to be printed on plain paper through a laser printer and digital copier with different paper sizes. The method utilizes an output buffer such that the original document needs to be scanned only once even though multiple copies are requested. The method adjusts input resolution to output device characteristics by manipulating the pulse width of the video signal and matching the number of output lines.

    摘要： The present invention relates to a frame buffer used by a laser printer controller to send video signals to a laser printer engine. The frame buffer allows software to have sufficient control of the dimension of the buffer and to have sufficient time to process data by allowing software to change X and Y dimensions of the buffer. In addition, software controls the loading of the frame buffer start address.
