The situation when The printer does not print via Wi-Fi. From a mobile device, this is a familiar scenario for many users of modern gadgets. You try to send a document or photo, but your device gets stuck in "Waiting" status or displays a connection error. The problem could be as simple as a router's frequency desynchronization or complex network security protocol settings.
Unlike a wired connection, wireless printing requires a perfect match of network parameters at both ends of the chain. Users often forget that Android And iOS Network requests are processed differently, and routers can isolate devices from each other for security reasons. Let's look at the main failure scenarios and troubleshooting methods.
Network environment and device status diagnostics
The first step should always be to check the physical condition of the equipment and basic connectivity. If printer If the error indicator is lit or flashing orange, the problem may not be Wi-Fi, but rather a lack of paper or a paper jam. Make sure the network displayed on your smartphone screen is the one your printer is connected to.
A common mistake is for devices to operate in different frequency bands. Many modern routers broadcast two networks: 2.4 GHz And 5 GHzOlder printer models often don't detect the 5 GHz network, even though the phone is connected to it by default. In this case, printing is impossible until the devices are on the same frequency segment.
⚠️ Note: Some routers automatically switch clients between frequencies (Smart Connect). If your printer is older, force separate networks in the router settings or temporarily disable the 5 GHz band for diagnostics.
It's also worth checking that guest network mode isn't enabled on your router. Guest profiles often have client isolation enabled, which prevents data exchange between your phone and printer, even if both are connected to the same router.
Protocol and driver compatibility issues
Modern printing from a phone is most often based on technology Wi-Fi Direct or cloud services. If you use standard OS tools, make sure that support AirPrint (for Apple) or Mopria (for Android) is enabled in the printer menu itself. Sometimes, after updating the router firmware, these services may be disabled.
In case of using proprietary applications (for example, HP Smart, Canon PRINT, Epson iPrint), the problem often stems from an outdated version of the program. Operating systems regularly change security policies, and older versions of applications may simply not be able to access the local network.
- 📱 Check for updates to the printing app in the official store.
- 🔄 Restart the print service in the printer settings via its control panel.
- 📶 Remove the device from the list of saved devices on your phone and add it again.
If the printer only supports WPA2 and the router is configured for WPA3, the connection may fail. This is a common issue when upgrading a router to a newer model with modern security standards enabled by default.
What is WPA3 and why does it break the seal?
WPA3 is the latest Wi-Fi encryption standard. It strengthens password security, but older printers (manufactured before 2018) are physically unable to work with this protocol. You should select a mixed WPA2/WPA3 mode in your router settings or temporarily switch to WPA2.
IP addressing and DNS conflicts
One of the most insidious reasons why the printer does not printThe problem is dynamic IP address changes. If a static IP address isn't reserved for the printer in the router settings, it may receive a new address after a reboot. The phone, however, continues to send print jobs to the old, inactive address.
To solve this problem, you need to go to the router's web interface. Find the section DHCP Server or LAN SettingsThere you need to find a list of connected clients, identify the printer by its MAC address, and assign a permanent IP address to it.
| Parameter | Default value | Recommended value | Impact on printing |
|---|---|---|---|
| Addressing type | Dynamic (DHCP) | Static | High (prevents device loss) |
| DHCP range | 100-200 | 50-99 | Average (avoids conflict) |
| Lease Time | 24 hours | Indefinitely (for statics) | Low |
It's also worth paying attention to your DNS servers. If your ISP blocks certain requests or your DNS is slow, cloud printing may not work. Try setting your phone's Wi-Fi settings to public DNS, such as Google's (8.8.8.8) or Cloudflare.
Security settings and firewalls
Antivirus software on your smartphone or your router's built-in firewall may block ports required for printing data. The standard port for the IPP (Internet Printing Protocol) is 631, and is often used for raw printing 9100If these ports are closed, the task simply won't reach its destination.
AP (Client Isolation) is often enabled in corporate or hotel networks. This feature is designed to prevent guests from seeing each other's computers, but it also completely disables printing. In home settings, this feature is also sometimes enabled accidentally or is activated in "Guest Network" mode.
⚠️ Important: Enabling AP Isolation mode in your wireless network settings will completely prevent your phone from seeing the printer. Make sure this option is disabled in your router's Wireless Settings.
Also check if your phone has a restriction on using the local network for a specific application. iOS When you first launch the printing app, the system asks for permission to access the local network. If you accidentally click "No," the app won't be able to find the printer.
Print and queue service failures
Sometimes the problem isn't with the connection, but with a "stuck" job. If the previous document didn't print due to an error, it can block the entire queue, creating the illusion that the printer is not workingMobile OSes do not always display the status of such a queue correctly.
It's necessary to completely clear the print queue. On Android, this can be done through the connected device's settings; on iPhone, through the notification center or the app you're printing from. In more complex cases, a complete reset of the printer's network settings can help.
☑️ Clearing the print queue
After clearing the queue, try printing a simple test page from the printer settings (without using your phone). If the test page prints, the mechanism is working properly, and the problem is definitely with the data transfer channel.
Specifics of Android and iOS operating systems
Platforms have their own characteristics. Android Installing a brand-specific printing plugin (such as HP Print Service Plugin) is often required. Without this system component, the phone simply won't see the device in the list of available devices. Updating Android can also reset permissions for these plugins.
Devices Apple Require AirPrint to be enabled. If your printer is older and doesn't natively support AirPrint, you'll have to resort to third-party intermediary apps that emulate the protocol. These apps are often paid or have limitations.
- 🍏 For iOS: Check if Bluetooth is turned on, as it is used to initially detect the device.
- 🤖 For Android: Go to
Settings → Connections → Additional settings → Printingand check the status of the plugins. - 🌐 For everyone: Make sure your phone isn't in Low Data Mode, which can limit background network activity.
Settings interfaces change, so search for menu items by keywords, not just by icons.
⚠️ Note: Wi-Fi and printing settings interfaces may differ depending on your router's firmware version or phone model. If you don't find an exact match, look for similarly named sections in the "Security" or "Advanced" categories.
Frequently Asked Questions (FAQ)
Why does the printer see the Wi-Fi network but not print?
Most likely, the device is connected to the router, but the phone is on a different subnet or client isolation is enabled. It's also possible that the printer's IP address has changed, and the computer or phone is accessing the old address.
Is it possible to print via Wi-Fi Direct without a router?
Yes, if your printer supports Wi-Fi Direct technology. This allows your phone to connect directly to the printer's signal, bypassing your home router. This is convenient if you don't have internet access but still need to print a document.
How to find the IP address of a printer?
On most models, the IP address can be found by printing a network configuration report (usually using a combination of buttons on the panel or via the "Report" menu). The address is also often displayed on the MFP screen in the network settings section.
Why did printing stop working after replacing the router?
The new router created a new network with a different name (SSID) and likely a different IP address range. The printer retains the old settings. You need to reconfigure the printer's connection to the new Wi-Fi network using the device menu or the WPS button.
