3. Method 2: Standard Android and iOS tools

If you don't want to install additional applications, you can use the built-in functions of the operating system. This method works for most modern printers that support AirPrint (For iOS) or Mopria (For Android).

For Android (via Mopria Print Service):

1. Make sure you have it installed on your smartphone. Mopria Print Service (usually pre-installed). If not, download it from Google Play.
2. Open the document or photo you want to print and select Seal (on the menu Share or through three dots).
3. Select your device from the printer list. If it's not there, click Add a printer and follow the instructions.
4. Set up print settings (number of copies, orientation, color) and confirm.

For iPhone/iPad (via AirPrint):

1. Open the file (in Photo, Mail, Safari or another application).
2. Click Share (square with an up arrow) and select Seal.
3. Your device will appear in the list of printers (if it supports AirPrint and connected to the same network).
4. Set the settings and click Seal.

If your printer does not appear in the list, check:

• 🔌 Does your model support AirPrint or Mopria (a list of compatible devices is available on the manufacturers’ websites).
• 🌐 Are the smartphone and printer on the same subnet (for example, both must be online) 192.168.1.x, and not in the router's guest network).
• 🔄 Is your antivirus or router firewall blocking the connection? (Try temporarily disabling protection.)

⚠️ Attention: Printers without support AirPrint/Mopria (for example, many models Brother before 2020) will not be visible in the standard print settings. In this case, use the manufacturer's app or Google Cloud Print (if still supported).

4. Method 3: Connecting via Wi-Fi Direct (if the printer does not support the router)

Wi-Fi Direct Allows you to connect your smartphone and printer directly, without the need for a router. This is useful if your printer is older or you're in a location without Wi-Fi access (for example, in an office with a limited network).

How to connect:

1. Activate the mode on the printer Wi-Fi Direct. This is usually done through an on-screen menu or a button on the panel (for example, Canon PIXMA MG3022 you need to hold down the button Wi-Fi for 5 seconds).
2. On your smartphone, open Settings → Wi-Fi and find the network with the printer name (for example, DIRECT-xx-Canon-MG3022).
3. Connect to this network. The password is usually on the printer's sticker or in the instructions (the default is often 12345678 or empty).
4. Open the document to print and select the printer from the list of devices (in Android (driver installation may be required).

Restrictions Wi-Fi Direct:

• 📵 While printing, your smartphone will not be connected to the Internet (you will have to switch between networks).
• 🖼️ Some applications (eg. Google Docs) may not see the printer in this mode.
• 🔋 The connection is broken when the printer or smartphone is turned off.

If the printer does not support Wi-Fi Direct, but he has USB port, can be used OTG cable for direct connection to a smartphone (not available on all models).

5. Troubleshooting common connection errors

Even with proper setup, glitches can still occur. Here are some common issues and how to fix them:

If nothing helps, reset the printer to factory settings (usually the button Reset on the rear panel) and set up the connection again. For printers HP It is also useful to use the utility HP Print and Scan Doctor (available on the official website).

6. Alternative ways to print from a smartphone

If the standard methods don't work, try these workarounds:

• ☁️ Cloud Printing: Upload the file to Google Drive, Dropbox or OneDrive, and then print via the printer's web interface (if it supports cloud services). For example, HP there is a function HP ePrint — the printer is assigned an email address to which documents can be sent.
• 🖥️ Printing via PC: If the printer is connected to the computer, use programs like TeamViewer or Chrome Remote Desktopto remotely start printing from your smartphone.
• 📡 USB-OTG: For printers without Wi-Fi (e.g. Brother HL-1110) can be used USB OTG cable and application PrinterShare (paid, but supports most models).
• 📱 Scan to PDF: If you need to scan a document but the printer won't connect, use apps like CamScanner or Adobe Scan - They will convert a photo into a PDF using AI.

The service is also suitable for office tasks. Google Cloud Print (Although it is officially closed, some printers still support it through workarounds). An alternative is Mopria Cloud Print, but it requires registration.

7. Optimize Wi-Fi for stable printing

If printing is constantly interrupted or is too slow, the problem may be with your router settings. Here's what you can do:

• 📶 Assign a static IP to the printer: In the router settings (section DHCP Reservation or IP binding) tie it Printer MAC address to a fixed IP. This will prevent connection drops.
• 🔄 Change Wi-Fi channel: If you have a lot of devices on your network, switch your router to a less crowded channel (for example, 1, 6 or 11 For 2.4 GHz). This can be done in the router's web interface (192.168.1.1 or 192.168.0.1).
• 🛡️ Turn off energy saving: Find the option in your router settings Wi-Fi Power Save or Green Mode and turn it off - this will eliminate delays when printing.
• 📡 Signal booster: If the printer is far from the router, use Wi-Fi repeater or Mesh system to improve coverage.

For printers that frequently go to sleep, disable the power saving mode in the device settings (usually Sleep Mode or Auto Off). This will increase power consumption, but will eliminate the need to constantly turn the printer on again.

⚠️ Attention: If your router uses WPA3 (new encryption standard), some older printers (Epson until 2019, Canon until 2020) may not connect. In this case, temporarily switch to WPA2-PSK in the router security settings.
