2. 使用打印机疑难解答
3. 安装所需的驱动程序
4. 调整 LAN Manager^{(Tweak LAN Manager)}身份验证级别
5. 手动添加本地打印机

继续^(Continue)阅读以详细了解这些步骤。

1]重新启动打印后台处理程序

Print Spooler服务允许您将打印机连接到您的计算机。如果此服务未运行，您将无法在计算机上看到打印机。如果您由于任何原因（或者，即使您没有）提前停止了它，您需要验证它是否正在运行。与任何其他背景一样，您可以在“ 服务^(Services)” 面板中找到它。

 在任务栏^(Taskbar)搜索框中搜索 服务^(services)，然后单击单个结果以在您的 Windows 10 计算机上打开服务。接下来，找出 Print Spooler 服务并双击它。

如果它显示为 Stopped，您需要单击 Start 按钮。

或者，如果它显示为 Running，请单击 Stop 按钮，然后 单击 Start ^(Start )按钮重新启动服务。

单击 确定 ^(OK )按钮以保存更改。

现在，重新启动计算机并检查问题是否仍然存在。

2]使用打印机疑难解答

由于Windows 10包含疑难解答程序，您可以使用 打印机疑难解答^{(Printer troubleshooter)} 程序来解决此类常见或基本问题。为此，请按 Win+I 打开Windows Settings。然后，转到 Update & Security > Troubleshoot > Additional troubleshooters 以 打开Windows 10 中的疑难解答页面。

打开后，找到 打印机^(Printer) 疑难解答，选择它，然后单击 运行疑难解答 ^{(Run the troubleshooter )}按钮。

接下来，您必须按照屏幕说明操作，因为您的计算机上的解决方案可能会有所不同。

3]安装所需的打印机驱动程序

购买打印机时，您会获得一张驱动程序 CD，它可以让您在计算机和打印机之间建立更好的连接。如果您尚未安装它，建议您安装并重新启动计算机。

但是，如果您的打印机没有自带驱动程序，您可以  在打印机制造商的官方网站上找到驱动程序。^{(find the driver on the official website)}

4]调整 LAN Manager^{(Tweak LAN Manager)}身份验证级别

LAN Manager身份验证级别允许您选择网络登录的身份验证协议——在本例中为网络打印机。可以使用本地组策略编辑器^{(Local Group Policy Editor)}和注册表编辑器^{(Registry Editor)}更改 LAN Manager 身份验证级别。

完成后，重新启动计算机以获取更改。

如果上述解决方案均无效，您可以手动添加打印机。以下步骤将为您完成这项工作。

FIX：打印机处于错误状态^{(Printer is in Error State)}。

5]手动添加本地打印机

在任务栏^(Taskbar)搜索框中搜索 控制面板 ^{(control panel )}，然后单击单个结果以打开计算机上的控制面板^{(Control Panel)}。然后，单击 设备和打印机^{(Devices and Printer)} 选项，然后单击 添加打印机 ^{(Add a printer )}按钮。

之后，您的计算机将搜索打印机。但是，您必须跳过它并单击 我想要的打印机未列出^{(The printer that I want isn’t listed)} 选项。

现在，选择 使用手动设置添加本地打印机或网络打印机^{(Add a local printer or network printer with manual settings)} 单选按钮，然后选择 下一步 ^(Next )选项。

之后，它会要求您选择现有端口或新端口。建议选择 Create a new port 并 从下拉列表中选择Local Port 选项。^{(Local Port )}

单击 下一步 ^(Next )按钮后，它会要求您输入端口名称。然后，您可以为本地打印机安装通用驱动程序。

最后，您需要重新启动计算机并检查它是否解决了问题。

就这样！这些是修复Windows无法连接到Windows 10上的打印机错误的有效解决方案。

1] Restart Print Spooler

The Print Spooler service lets you connect the printer to your computer. If this service is not running, you cannot see the printer on your computer. In case you stopped it earlier due to any reason (or, even if you didn’t), you need to verify if it is running or not. Like any other background, you can find it in the Services panel.

Search for services in the Taskbar search box, and click on the individual result to open Services on your Windows 10 computer. Next, find out the Print Spooler service and double-click on it.

If it is showing as Stopped, you need to click on the Start button.

Alternatively, if it shows as Running, click the Stop button, and Start button to restart the service.

Click the OK button to save the change.

Now, restart your computer and check if the problem remains or not.

3] Install required Printer drivers

When you bought the printer, you got a driver CD with it, which lets you establish a better connection between your computer and the printer. If you haven’t installed it already, it is suggested to do that and restart your computer.

However, if you haven’t got it with your printer, you can find the driver on the official website of the printer manufacturer.

4] Tweak LAN Manager authentication level

The LAN Manager authentication level lets you choose the authentication protocol for network logons – in this case, network printer. It is possible to change the LAN Manager authentication level using the Local Group Policy Editor and the Registry Editor.

Once done, restart your computer to get the change.

If none of the aforementioned solutions is working, you can add your printer manually. The following steps will do the job for you.

5] Manually add a local printer

Search for the control panel in the Taskbar search box, and click on the individual result to open Control Panel on your computer. Then, click on the Devices and Printer option, and click the Add a printer button.

After that, your computer will search for printers. However, you have to skip it and click The printer that I want isn’t listed option.

Now, select the Add a local printer or network printer with manual settings radio button and choose the Next option.

Following that, it asks you to choose an existing port or a new port. It is suggested to select the Create a new port and choose the Local Port option from the drop-down list.

Once you click the Next button, it asks you to enter the port name. Then, you can install the generic drivers for your local printer.

At last, you need to restart your computer and check if it solves the issue or not.
