It's quite common to need to urgently print a ticket, contract, or photo, but only have a smartphone and a printer, but no Wi-Fi connection. Many users mistakenly believe that printing requires a router and internet connection, but modern technology allows for a direct connection between devices.
There are several reliable ways to bypass the lack of a local network. You can use direct cable connection, use technology Wi-Fi Direct, built into most modern models, or use cloud services if your printer has its own communication module. The choice of method depends on the type of device you have (Android or iOS) and the technical capabilities of your printer.
In this article, we'll go over each of the available options in detail so you can choose the one that best suits your situation. No matter what your Hewlett-Packard, Canon or Epson — Most interfaces operate on similar principles. The main thing is to configure the connection settings correctly before sending a task.
Using a USB cable and OTG adapter
The most stable and time-tested method of data transfer is a physical connection. To implement this method, you will need a special adapter known as OTG adapter (On-The-Go). It allows you to connect a standard USB cable from your printer to your smartphone's charging port.
For owners of devices based on Android You're more fortunate, as support for external peripherals is implemented at the kernel level in this system. Simply plug the cable into the phone's port, and the system should automatically detect the new hardware. In some cases, you'll need to install drivers or a specialized application from the manufacturer.
For users iPhone And iPad To connect a USB printer, you will need an adapter Lightning to USB Camera Adapter or an equivalent for the connector USB-CIt's important to note that some printer models consume more power than the phone's port can handle, so an adapter with additional power may be required.
⚠️ Note: Not all smartphones support the OTG function. Before purchasing an adapter, check the specifications for your model on the manufacturer's official website or in the app.
CPU-Z.
The setup process is usually straightforward. After physically connecting, open the document you want to print, select the print menu, and find your printer in the list of available devices. If it doesn't appear automatically, go to the printing settings and add it manually via USB.
Wi-Fi Direct technology: printing without a router
Technology Wi-Fi Direct Allows devices to connect directly to each other, without the need for an access point or router. In this case, the printer itself creates a mini-network to which your phone connects. This is ideal if your router is broken or you're in a location without Wi-Fi infrastructure.
To get started, you need to activate direct connection mode on the printer itself. This is usually accomplished by pressing a button with the corresponding icon on the control panel or by selecting an option in the network settings menu. Once enabled, the network name and connection password will appear on the printer screen (or on the printed report).
The user's next steps are as follows:
- 📱 Open Wi-Fi settings on your smartphone.
- 🔍 Find the name of your printer in the list of available networks (often contains the model, for example, HP-Print-25-DeskJet).
- 🔑 Enter the password indicated in the instructions or on the device screen.
- 🖨️ Open the document and select Print, making sure the correct printer is selected.
It is important to understand that when connecting via Wi-Fi Direct Your phone may temporarily lose internet access if it doesn't support dual Wi-Fi. This means you'll be able to print documents, but won't be able to view web pages while printing.
The connection in this mode is quite stable, but the range is limited to a few meters. Make sure the phone and printer are within direct line of sight to avoid data packet loss.
Printing via cloud services and mobile internet
If your printer has a Wi-Fi module and supports cloud technologies, you can print a document using your phone's mobile data (3G/4G/5G). In this case, both devices must be connected to the internet, but they don't even need to be on different networks, although for home printing, they are typically located close to each other.
The most popular solutions are: Google Cloud Print (Although the service is closing, its functions are integrated into Android), HP ePrint, Epson Connect or Canon PRINTThe operating principle is that the document is sent to the manufacturer's server, and from there it is transmitted to the printer.
To set up this method, follow these steps:
- ☁️ Register your printer in the manufacturer's cloud service through the control panel.
- 📧 Get a unique printer email address or link the device to your account.
- 📲 Install the corresponding application on your phone and log in to your account.
- 📤 Send a document to print via the app using mobile data.
⚠️ Please note: Using cloud printing will use your mobile data plan. Make sure you have an unlimited data plan or sufficient data plan, especially when printing large files with graphics.
The advantage of this method is the ability to print from anywhere in the world. You can send a document to print from the office, and it will print at home as long as the printer is turned on and connected to the network.
Connection specifics for Android and iOS
Operating systems have their own specific features for working with peripheral devices. In the ecosystem Apple the main emphasis is on technology AirPrintIt allows you to print without installing drivers if the devices are on the same network or connected via Wi-Fi Direct (if the printer supports it). AirPrint over Wi-Fi Direct).
On devices Android The situation is more varied. Starting with version 4.4, the system has a built-in printing plugin, but older printer models or specific features may require a separate plugin, such as Mopria Print ServiceThis is a universal driver that supports most modern models.
A comparison of platform capabilities is presented in the table below:
| Characteristic | Android | iOS (iPhone/iPad) |
|---|---|---|
| Basic technology | Mopria / Print Plugin | AirPrint |
| USB (OTG) support | Depends on the phone model | Requires original adapter |
| The need for applications | Often required | Rarely (built into the system) |
| Work without a router | Wi-Fi Direct / USB | AirPrint Direct / USB |
If you are the owner Android, it is recommended to install the application in advance Mopria Print Service from the store Google PlayThis will expand compatibility with older or less common printer models that are not detected by the system by default.
What should I do if AirPrint doesn't see my printer?
Make sure Wi-Fi is enabled on both your iPhone and printer. If your router isn't enabled, check if your printer supports AirPrint Direct. In some cases, you may need to restart both devices.
Using NFC for instant printing
Technology NFC (Near Field Communication) allows data transfer over very short distances by simply touching devices together. This is the fastest way to initiate printing if your smartphone and printer are equipped with the appropriate modules.
To use this method, you don't need to search for a network or enter passwords. Simply hold your phone near a special area on the printer (usually marked with a logo). NFC). The system will automatically recognize the device, establish a connection (usually via Wi-Fi Direct), and offer to print the open document.
However, there's a catch: NFC is only used for the handshake and command transmission. The actual document file will be transmitted via a different channel, usually the same one. Wi-Fi DirectTherefore, the basic wireless network settings must still be correct.
⚠️ Important: Make sure your smartphone's screen is unlocked and NFC is enabled in settings before attempting to connect. Some phone models have NFC disabled by default to save battery.
This method is especially convenient in offices or public places where you need to quickly print material from a guest's phone without requiring the password for the main Wi-Fi network.

Troubleshooting connection issues
Even if you follow all the instructions, technical difficulties may arise. Often, the problem lies in the phone not seeing the printer in the list of available devices. First, check that the printer's discovery feature is enabled. Some models go into sleep mode and stop transmitting a signal.
Another common issue is file format incompatibility. The printer may support image printing. JPEG and documents PDF, but will not be able to process files DOCX or specific spreadsheet formats without prior conversion. In such cases, use converter apps or send the file through the manufacturer's proprietary app.
If the connection keeps dropping, try changing the Wi-Fi channel in your router settings (if applicable) or moving away from sources of interference, such as microwave ovens or Bluetooth headsets. Also, make sure your phone isn't in "Data Saver" mode, which can block local transfers of large files.
Frequently Asked Questions (FAQ)
Is it possible to print photos from a phone if the printer is very old and does not have Wi-Fi?
