Android USB Printing — How to Connect a USB Thermal Printer to Your Android Phone
Android USB printing lets you connect a thermal printer directly to your Android phone using a USB OTG cable — no Bluetooth pairing, no wireless dropouts, no re-connecting. If you run a billing counter, POS desk, or receipt-heavy operation, USB printing on Android gives you the most stable and reliable connection possible.
This guide explains how to print from Android via USB, which app to use, what printers are compatible, and how to set it up in under 5 minutes.
What Is Android USB Printing?
Android USB printing uses the USB OTG (On-The-Go) feature built into most Android phones. OTG lets your phone act as a USB host — the same way a laptop connects to a printer via USB. With a small OTG adapter or cable, you plug the printer directly into your Android phone and print over a wired connection.
The app that makes this work is Bluetooth-USB Printer Plus — it supports both Bluetooth and USB ESC/POS thermal printers on Android, making it the most versatile thermal printing app available.
Why USB Printing on Android Is Better Than Bluetooth (For Fixed Setups)
| USB Printing (OTG) | Bluetooth Printing | |
|---|---|---|
| Connection | Wired — zero dropouts | Wireless — can drop signal |
| Setup | Plug in and print immediately | Pair device first |
| Speed | Faster for large print jobs | Good for small receipts |
| Interference | None | Possible in crowded RF areas |
| Best use | Fixed POS counter, billing desk | Mobile, handheld printing |
For a shop billing counter or restaurant POS where the printer is always next to the phone, USB is the better choice. You plug in once and the connection never drops — even during peak hours with multiple Bluetooth and Wi-Fi signals competing nearby.
What You Need for USB Printing on Android
- An Android phone with USB OTG support — most Android phones from 2016 onwards support OTG
- A USB OTG cable or adapter — USB-C to USB-A, or Micro-USB to USB-A (depends on your phone)
- Any ESC/POS USB thermal printer (58mm or 80mm)
- Bluetooth-USB Printer Plus installed on your phone (free to download)
How to Set Up USB Printing on Android — Step by Step
Step 1 — Connect the USB printer to your Android phone
Use a USB OTG cable to connect your Android phone to the printer’s USB port. As soon as you plug in, Android detects the USB device automatically. No drivers needed — the app uses Android’s built-in USB Host API.
Step 2 — Open Bluetooth-USB Printer Plus
Open the app. It automatically scans for connected USB printers. Any printer detected as a USB Class 7 (printer) device will appear in the list with its manufacturer name and product name (for example: Xprinter XP-58 or Epson TM-T82).
Step 3 — Allow USB permission
Android shows a one-time popup: “Allow Bluetooth-USB Printer Plus to access the USB device?” Tap OK. Tick Use by default for this USB device so the permission is remembered for next time.
Step 4 — Select the USB printer and print
Tap the printer in the list to connect. Now type your content, pick a template, or use the AI template generator — then tap Print. The job sends directly to the USB printer. For large print jobs, the app sends data in 4KB chunks so nothing times out or gets cut off.
Note: You can switch between USB and Bluetooth printing in the same app. If your counter printer is USB and your handheld printer is Bluetooth, one app handles both.

Troubleshooting Android USB Printing Problems
USB printer not detected on Android
- Confirm your phone supports USB OTG — check your model’s spec sheet or search “[your phone model] USB OTG support”.
- Try a different OTG cable or adapter — some cables only carry charging current, not data.
- Make sure the printer is switched on before plugging in.
- Unplug and re-plug the cable to trigger Android’s USB detection again.
USB permission dialog doesn’t appear
- Force-stop the app, unplug the cable, restart the printer, then re-plug and reopen the app.
- On some phones, go to Settings → Developer Options → USB configuration and set it to “MTP” or “File Transfer” first, then switch back.
Print job sent but nothing prints
- Run the printer’s self-test (hold the feed button while powering on) to confirm it works independently.
- Check the printer is in ESC/POS mode — some models support multiple protocol modes.
- Try a plain text print first (no images) to confirm the connection is working.
Printing stops midway through a large document
- This is rare with Bluetooth-USB Printer Plus because it sends data in 4KB chunks rather than all at once. If it happens, try reducing image quality or splitting large jobs.
Frequently Asked Questions — Android USB Printing
Can I print from Android to a USB printer without a computer?
Yes. With Bluetooth-USB Printer Plus and a USB OTG cable, your Android phone connects directly to the USB printer — no PC, no Wi-Fi, no drivers needed.

You need a USB OTG cable or adapter — USB-C to USB-A (for newer phones) or Micro-USB to USB-A (for older phones). These cost very little and are widely available.
Can I use USB and Bluetooth on the same app?
Yes. Bluetooth-USB Printer Plus supports both connection types. You can switch between a USB counter printer and a Bluetooth handheld printer within the same app session.
What Android version is needed for USB OTG printing?
Android 5.0 (Lollipop) and above. Most phones from 2016 onwards meet this requirement. Bluetooth-USB Printer Plus is compatible with Android 5.0+.
Is USB printing faster than Bluetooth on Android?
For large print jobs (multi-line receipts, images, barcodes), USB is noticeably faster. For small receipts it’s similar. The main advantage of USB is stability, not just speed.
