Printer and process for printing different size dots by setting drive energies based on adjacent data bit logic
摘要：
An LED printer includes a printing control unit and an LED head. When a video signal received at the control unit has a higher resolution than the LED head, the control unit carries out the logical AND between successive bit data of the video signal to convert the video signal to a first signal. Corresponding to a line timing signal, this first signal is transferred as a head data signal to the LED head and is then printed on a basic raster scanning line. Further, the control unit also carries out the exclusive-OR between the successive bit data of the video signal so that the video signal is converted to a second signal and outputted to a line buffer. Corresponding to an additional line timing signal, the second signal is transferred as another head data signal to the LED head and is printed on an additional raster scanning line. The LED head drive energy for performing printing along the basic raster scanning line is set independently.
摘要（中）：

LED打印机包括打印控制单元和LED头。 当在控制单元处接收的视频信号具有比LED头更高的分辨率时，控制单元执行视频信号的连续位数据之间的逻辑“与”，以将视频信号转换为第一信号。 对应于行定时信号，该第一信号作为头数据信号传送到LED头，然后印在基本光栅扫描线上。 此外，控制单元还执行视频信号的连续位数据之间的异或，使得视频信号被转换为第二信号并输出​​到行缓冲器。 对应于附加线路定时信号，第二信号作为另一个头数据信号传送到LED头，并被印刷在附加的光栅扫描线上。 用于沿着基本光栅扫描线执行打印的LED头驱动能量是独立设置的。
