Apple 的AirPrint技术让您可以轻松地从 iPhone 以无线方式将打印作业发送到打印机。您可以打印网页、图像、笔记和其他文档的硬拷贝，而无需移动一英寸或插入电缆。您只需要一个 Wi-Fi 连接和一台兼容的打印机。
AirPrint技术快速、直观且易于使用。然而，在某些情况下，您的 iPhone 无法找到您的打印机。如果这描述了您目前的情况，我们编制了 11 个故障排除步骤，可帮助您解决问题。本指南中的建议也适用于 iPad。
注意：(Note:) AirPrint不适用于蜂窝或移动数据。
1.确认打印机支持AirPrint(Printer Supports AirPrint)
您的打印机不会显示在您的 iPhone 上？那可能是因为打印机不支持AirPrint。检查打印机的机身或说明手册是否有“与Apple AirPrint一起使用”标签。
还有其他方法可以确认打印机是否兼容AirPrint 。访问制造商网站上的产品页面或查看Apple 网站上的 AirPrint 信息页面(AirPrint info page on Apple’s website)。
在Apple网站上，您可以找到支持AirPrint技术的设备（打印机、服务器等）的完整列表。如果您的打印机不在列表中，它很可能不支持AirPrint。我们建议您阅读本指南，了解如何从您的 iPhone 打印到未启用 AirPrint 的打印机(printing to a non-AirPrint enabled printer from your iPhone)。
2.打印机工作正常(Printer Working Correctly)吗？
您有一台支持 AirPrint 的打印机，但它没有显示在您的 iPhone 上。你做什么工作？对于初学者，请确保打印机已开机并处于活动状态。根据类型或型号的不同，某些打印机会在一段时间不活动后进入“睡眠模式”或“低功耗状态”。
按(Press)打印机的电源按钮将其打开。您还应该检查打印机的状态指示灯或屏幕是否有任何错误消息或警告。通常，闪烁或稳定的红灯表示打印机存在问题。有关更多解决方案，请参阅我们关于修复 Wi-Fi（无线）打印机(fixing Wi-Fi (wireless) printers)的故障排除指南。
3.将iPhone 和打印机(Printer)连接(Connect)到同一网络(Same Network)
为了让您的 iPhone 找到您的打印机，您的 iPhone 和打印机必须在同一个无线网络上。如果您的 iPhone 上未显示支持 AirPrint 的打印机，请前往打印机的网络设置并确保其Wi-Fi已启用。最重要的是，确保打印机连接到与iPhone相同的Wi-Fi网络。(Wi-Fi)
如果问题仍然存在，打印机可能在网络上被阻止或列入黑名单。转到路由器的设置并将打印机列入白名单(whitelist the printer)。
还值得一提的是，由于 Wi-Fi 信号较弱，您的 iPhone 可能无法检测到AirPrint打印机。(AirPrint)确保(Make)两个设备（iPhone 和打印机）都靠近路由器，干扰最小。
4.切换到专用网络
Apple关心您的文件和文档的安全，因此AirPrint无法在不安全的公共网络上运行。黑客可以轻松拦截您在公共网络上发送（到您的打印机）的文件。
如果您的 iPhone 和打印机连接到公共Wi-Fi网络，您将始终收到“未找到 AirPrint 打印机”错误。将您的设备切换到受密码保护的私有网络，然后重试。
5. 重新启用 Wi-Fi
刷新两台设备（即您的 iPhone 和打印机）的 Wi-Fi 连接可能会解决此问题。从控制中心(Control Center)或“设置”(Settings)应用程序关闭 iPhone 的 Wi-Fi - 转到“设置”(Settings) > “ Wi-Fi ”并关闭“ Wi-Fi ” 。几秒钟后重新启用Wi-Fi并加入无线网络。
前往打印机的设置菜单并执行相同操作：禁用Wi-Fi，等待几秒钟，重新打开，然后加入 iPhone 所连接的同一个无线网络。
如果您的无线打印机没有 LED 显示屏或屏幕，请注意物理Wi-Fi按钮。如果您找不到Wi-Fi按钮或不知道哪个按钮控制打印机的Wi-Fi ，请查看打印机的使用说明书。
6.重启你的 iPhone
在您关闭手机或使用其他 iPhone（或 iPad）将文件发送到AirPrint打印机之前。如果其他 iOS 设备可以找到打印机，则意味着您的 iPhone 是问题所在。关闭(Shut)手机并再次尝试连接到打印机。
7. 重启打印机
重启打印机可以解决常见的打印机相关问题(common printer-related issues)。如果您的AirPrint打印机在同一个(AirPrint)Wi-Fi网络中的多部 iPhone 上没有显示，请重新启动打印机并重试。
8.重新启动或重置您的路由器
您的路由器也可能是问题所在。关闭(Shut)路由器并重新打开。然后(Afterward)，将您的 iPhone 和打印机连接到网络并尝试无线打印文件。
如果AirPrint打印机仍然丢失，或者您的 iPhone 一直显示“未找到AirPrint打印机”错误，请重置路由器并重(reset the router)试。
9.硬重置打印机
如果打印机仍然无法检测到，请考虑将其重置为出厂默认设置。请注意，硬重置您的打印可能会删除一些配置，如纸盘大小、页数、语言等。重置打印机时，您需要重做这些设置和首选项。
10. 重置 iPhone 的网络设置
对一些 iPhone 用户(some iPhone users)来说，执行网络重置很神奇。转到设置(Settings)>常规(General)>重置(Reset)>重置网络设置(Reset Network Settings)并输入您的iPhone密码以继续。单击确认提示上的重置网络设置，您的设备将重新启动。(Reset Network Settings)
当您的 iPhone 重新开机时，加入托管AirPrint打印机的同一个(AirPrint)Wi-Fi网络并尝试打印文件。
11. 降级或更新你的 iPhone
iOS 更新也有破坏 AirPrint 功能稳定性的历史(history of destabilizing the AirPrint functionality)。因此，如果您发现 iPhone 在安装新的操作系统更新后停止检测您的打印机，您可以回滚到之前的 iOS 版本(roll back to a previous iOS version)。
此外，如果您运行的是旧的或过时的 iOS 版本， AirPrint也可能无法工作。(AirPrint)转到设置(Settings)>常规(General)>软件更新(Software Update)并在页面上安装任何可用的更新。
不带路由器的 AirPrint
一些支持 AirPrint 的高端打印机可以托管Wi-Fi热点。如果您有一台这样的打印机，请创建一个热点，转到您 iPhone 的Wi-Fi菜单，然后点击您的打印机名称以加入网络。当您要打印文件时，您可以在打印机(Printer) 选项(Options)页面上找到打印机。
如果您没有时间尝试上面列出的故障排除技术，请使用此解决方法快速打印文件。但是，如果您的 iPhone 仍然找不到打印机，您应该与（打印机的）制造商联系。
Can’t Find Your AirPrint Printer on iPhone? 11 Ways to Fix
Apple’s AirPrint tесhnology makes it so easy to wirelessly send print jоbs to a printer from your iPhone. Yоυ can prіnt hard copies of web pages, images, notes, and other dоcuments without moving an inch or plugging a cable. Αll you need is a Wi-Fi connection and a compatible printer.
The AirPrint technology is fast, intuitive, and easy to use. Yet, there are instances when your iPhone can’t find your printer. If this describes your present situation, we’ve compiled 11 troubleshooting steps that’ll help you fix the problem. The recommendations in this guide are also applicable to iPads.
Note: AirPrint doesn’t work with cellular or mobile data.
1. Confirm That the Printer Supports AirPrint
Your printer won’t show up on your iPhone? That could be because the printer doesn’t support AirPrint. Examine the printer’s body or instruction manual for a “Works with Apple AirPrint” label.
There are other ways to confirm if a printer is AirPrint compatible. Visit the product page on the manufacturer’s website or check the AirPrint info page on Apple’s website.
On the Apple website, you’ll find a comprehensive list of devices (printers, servers, etc.) that support the AirPrint technology. If your printer isn’t on the list, it most likely doesn’t support AirPrint. We recommend reading this guide on printing to a non-AirPrint enabled printer from your iPhone.
2. Is the Printer Working Correctly?
You have an AirPrint-enabled printer but it’s not showing up on your iPhone. What do you do? For starters, ensure the printer is powered on and active. Some printers, depending on the type or model, enter a “sleep mode” or “low-power state” after a certain period of inactivity.
Press the printer’s power button to turn it on. You should also check the printer’s status lights or screen for any error message or warning. Usually, a flashing or solid red light indicates an issue with the printer. Refer to our troubleshooting guide on fixing Wi-Fi (wireless) printers for more solutions.
3. Connect iPhone and Printer to the Same Network
For your iPhone to find your printer, your iPhone and the printer must be on the same wireless network. If an AirPrint-enabled printer isn’t showing up on your iPhone, head to the printer’s network settings and ensure its Wi-Fi is enabled. Most importantly, make sure the printer is connected to the same Wi-Fi network as your iPhone.
If the problem persists, the printer could be blocked or blacklisted on the network. Go to the router’s settings and whitelist the printer.
It’s also worth mentioning that your iPhone may fail to detect an AirPrint printer due to a weak Wi-Fi signal. Make sure both devices (the iPhone and printer) are in close proximity to the router with minimal interference.
4. Switch to a Private Network
Apple cares about the safety of your files and documents, so AirPrint doesn’t work on unsecured public networks. Hackers can easily intercept files that you send (to your printer) on a public network.
If your iPhone and printer are connected to a public Wi-Fi network, you’ll always get a “No AirPrint Printers Found” error. Switch your devices to a private, password-protected network and try again.
5. Re-Enable Wi-Fi
Refreshing the Wi-Fi connection for both devices (i.e. your iPhone and printer) might fix the issue. Turn off your iPhone’s Wi-Fi from the Control Center or the Settings app—go to Settings > Wi-Fi and toggle off Wi-Fi. Re-enable Wi-Fi after some seconds and join a wireless network.
Head to your printer’s settings menu and do the same: Disable Wi-Fi, wait some seconds, turn it back on, and join the same wireless network that your iPhone’s connected to.
If your wireless printer doesn’t have an LED display or screen, look out for a physical Wi-Fi button. Check the printer’s instruction manual if you can’t find a Wi-Fi button or don’t know which button controls the printer’s Wi-Fi.
6. Restart Your iPhone
Before you shut down your phone or you’re using a different iPhone (or iPad) to send files to the AirPrint printer. If other iOS devices can find the printer, that means your iPhone is the problem. Shut down your phone and try connecting to the printer again.
7. Restart the Printer
Power-cycling your printer can resolve common printer-related issues. If your AirPrint printer doesn’t show up on multiple iPhones despite being on the same Wi-Fi network, restart the printer and try again.
8. Restart or Reset Your Router
Your router could also be the problem. Shut down the router and turn it back on. Afterward, connect your iPhone and printer to the network and try printing a file wirelessly.
If the AirPrint printer is still missing, or your iPhone keeps displaying a “No AirPrint Printers Found” error, reset the router and try again.
9. Hard Reset the Printer
Should the printer remain undetectable, consider resetting it to factory default settings. Note that hard resetting your printing may erase some configurations like tray size, page count, language, etc. You’ll need to redo these settings and preferences when you reset your printer.
10. Reset iPhone’s Network Settings
Performing a network reset worked magic for some iPhone users. Go to Settings > General > Reset > Reset Network Settings and enter your iPhone’s passcode to proceed. Click Reset Network Settings on the confirmation prompt and your device will restart.
When your iPhone comes back on, join the same Wi-Fi network hosting the AirPrint printer and try printing a file.
11. Downgrade or Update Your iPhone
iOS updates also have a history of destabilizing the AirPrint functionality. So, if you noticed your iPhone stopped detecting your printer after installing a new OS update, you can roll back to a previous iOS version.
Also, AirPrint can also fail to work if you’re running an old or outdated iOS version. Go to Settings > General > Software Update and install any available update on the page.
AirPrint Without a Router
Some high-end AirPrint-enabled printers can host a Wi-Fi hotspot. If you have one such printer, create a hotspot, go to your iPhone’s Wi-Fi menu and tap your printer’s name to join the network. When you want to print a file, you’ll find the printer on the Printer Options page.
Use this workaround to quickly print a file if you don’t have time to try the troubleshooting techniques listed above. However, if your iPhone still can’t find the printer, you should get in touch with the (printer’s) manufacturer.
