1、下载HP1020固件文件sihp1020.dl文件至/etc目录
2、在USB热拔插触发目录下建立触发脚本：VI /etc/hotplug.d/usb/Printer-HP1020
#!/bin/sh set -e # 固件路径 FIRMWARE=/etc/sihp1020.dl # 打印机路径，可以从OpenWRT的USB打印机界面中中查看 DEVICE=/dev/usb/lp0 # Debug Log File LOGFILE=/tmp/hp1020 if [ "$PRODUCT" = "3f0/2b17/100" -a "$ACTION" = "bind" -a "$DEVTYPE" = "usb_device" ]; then echo "$(date): USB printer binded. Trying to upload firmware..." >> $LOGFILE cat $FIRMWARE > $DEVICE echo "$(date): Success. Done." >> $LOGFILE exit fi
加入首次启动 local startup /etc/rc.local
cat /etc/sihp1020.dl >> /dev/usb/lp0
3、实现效果：
打印机开机后触发USB热插拔事件，HP1020打印机绿灯常亮并立即进行自检，然后红灯绿灯交替闪烁再次自检，随后绿灯常亮
