先确认型号是 LJ2400，再核对系统版本和连接方式；如果型号、位数、端口都对，再继续修复服务层问题。
方法1 自动识别并安装驱动
新电脑首次连接 LJ2400 时，先让系统识别硬件，避免直接运行不匹配安装包。
操作步骤
- 将联想 LJ2400 通过 USB 线直连电脑后置接口，打开打印机电源。
- 按 `Win+X` 打开设备管理器，查看「打印队列」或「其他设备」下是否出现异常设备。
- 右键异常设备，选择「更新驱动程序」→「自动搜索驱动程序」。
- 如果系统无法匹配，记录 Windows 版本和系统位数，再按型号搜索对应驱动。
方法2 清理旧版驱动后重装
旧版驱动包残留会让新驱动安装失败，尤其是从 Windows 7/8 升级到 Windows 10/11 后。

操作步骤
- 按 `Win+R` 输入 `services.msc`，找到 Print Spooler，确认启动类型为「自动」。
- 服务停止时点击「启动」，再重新打开打印队列观察状态。
- 以管理员身份执行 `sfc /scannow`，等待系统文件检查完成。
- 继续执行 `DISM /Online /Cleanup-Image /RestoreHealth`，完成后重启并打印测试页。
方法4 核对 USB 端口和线缆
联想 LJ2400 是常见 USB 打印机，端口漂移或线缆不稳会让驱动看似正常但无法打印。
操作步骤
- 打开控制面板→设备和打印机，右键 Lenovo LJ2400，进入「打印机属性」→「端口」。
- 确认勾选的是当前 USB 虚拟端口，例如 `USB001` 或 `USB002`。
- 更换 USB 线，避免通过扩展坞或前置接口连接。
- 打印测试页，如果能输出，就不要继续更换驱动版本。
