打印机驱动完全清除

HP LaserJet printers are equipped with a set of advanced features to help you stay productive and reduce paper waste. To completely clear out a HP LaserJet printer, you will need to reset it to the original factory settings. To do this, ensure that the printer is powered off and unplug the power cord from the wall outlet. While the printer is powered off, press and hold the Go button until all the LED lights on the printer come on. After all the lights have lit up, release the Go button. The printer will now enter a "factory reset" mode. Once it is finished, power the printer back on and it will be completely cleared out.
