1 针式打印机原理
- 针式打印机16针是纵向排列，每次打印垂直的16bit，然后右移一bit，继续下列打印；字节的MSB表示最上面的点，字节LSB表示最下面的点
- 由于汉字字模的点阵是横向排列的，而提供给打印头的信息却需要按纵向排列，所以必须再对字模缓冲区中存放的字模数据进行变换，变成打印机按图形方式工作时所需要的数据格式才能送出
- 参考Nokia5110和JLX12864的字符显示原理

USB BH reset：Bigger Hammer or Brad Hosler，表示warm reset；you may be confused why the USB 3.0 spec calls the same type of reset "warm reset" in some places and "BH reset" in other places. "BH" reset is supposed to stand for "Big Hammer" reset, but it also stands for "Brad Hosler". Brad died shortly after the USB 3.0 bus specification was started, and they decided to name the reset after him. The suggestion was made shortly before the spec was finalized, so the wording is a bit inconsistent.
