涉事设备

  • EPSON L3150 Series

    出现情况

    在打印过的机器上，都连不上打印机。

    解决方案

    相关设备情况

    办公用电脑，不可能用太专业的方式解决。基本基于纯办公的Windows系统，和不麻烦的解决方案。

    重连打印机

    需要信息

    IP

    查看方式（3种）

    最简单但是有前提条件：Scanner

    因为是一个打印扫描一体机，计算机安装了其他的扫描组件，用Scanner扫描的时候，因为原始的IP连不上，会提示重新选择，此时会对网段进行扫描，就有了：

    最简单但是需要打印一次：硬件的打印信息

    在打印机上，很多按键，单独按和组合按有不同的效果：《打印机 - 打印自检页》：
    image.png
    有一个按键是打印“信息”的，其中一部分是“网络信息”，在“网络信息”中有此时打印机所用的IP：
    image.png
    成本是需要打印一次，有用过的纸的话，最好用用过的纸，环保一点。

    有点麻烦没想到有什么必要：Ping该网段使用的IP

    ping打印机所在网段的IP（可以用“arp -a”），有2个问题：

  • 其他同网段存活的设备很多

    • 需要确认存活的设备是打印机
      • 虽然我最后确认了打印机返回包的文字特征，但是在黑盒状态下，略麻烦，不好控制

        返回报文（适合黑盒）
