To connect a Wi-Fi printer to your phone, follow these general steps:

1. **Connect both your phone and printer to the same Wi-Fi network.** Your phone must be on the printer’s Wi-Fi network — printing will not work over cellular data (e.g., 4G/5G)[1].

2. **On your phone, enable the printing service:**
– For Android: Go to **Settings** > search for **Printing** > select **Default Print Service** and turn it on. Your phone will scan for compatible printers on the same network and list them[1].
– If your printer isn’t found, choose **Add service** within the printing settings, download the app or service for your printer’s brand, then select your printer following those steps[1].

3. **For iPhone users:**
– Use **AirPrint**, which allows wireless printing to compatible printers on the same Wi-Fi network. Make sure both devices are connected to the same Wi-Fi. Open the document or photo, tap **Share** > **Print**, and select your AirPrint-enabled printer (Apple devices generally don’t support Bluetooth printing to printers)[1].

4. **Optional NFC connection (if supported):**
Enable NFC on your phone and tap your phone to the printer’s NFC mark to establish a connection and begin printing[1].

5. **You can also use manufacturer apps (e.g., HP Smart app for HP printers) for setup and advanced features, including scanning and managing print jobs directly from your phone[2][4].**

This process works for most major printer brands like Canon, HP, Epson, and Brother. If you have a specific printer model, using the manufacturer’s app or documentation may provide tailored instructions.

In brief: Connect printer and phone to the same Wi-Fi, enable printing on phone, select printer from the list, and start printing. For iPhone, use AirPrint; for Android, use Default Print Service or brand-specific apps[1][2][4].
