How to Print from Phone to USB Printer Without OTG Cables or Apps

If you search the internet for “how to print from phone to USB printer”, almost every article and YouTube tutorial tells you to do the same thing:

1. Buy a USB-C OTG (On-The-Go) adapter cable.
2. Physically plug the printer’s heavy USB-B cable into your phone.
3. Download an ad-supported third-party app like NokoPrint or PrinterShare.
4. Hope the app recognizes your specific printer model.

While an OTG cable technically works, it is inconvenient. Your phone is physically tethered to the printer by a cable, you cannot print from across the room, and most third-party printer apps bombard you with ads or require paid subscriptions just to print a multi-page document.

There is a much cleaner, wireless way: use your existing Windows PC as a wireless LAN bridge.

Why You Don’t Need an OTG Cable

Most households and offices already have their USB printer plugged into a Windows laptop or desktop PC.

The computer already has the correct manufacturer printer driver installed, knows how to communicate with the printer, and is connected to your home Wi-Fi network.

By running Printman on your Windows PC, you can convert that wired USB printer into a real wireless network printer accessible to any phone or tablet on your Wi-Fi.

Option A: Native Phone Print Dialog (printman share)

If you want the printer to appear automatically in the standard iOS Share Sheet or Android Print Dialog without opening any browser or installing any app:

1. Download the Printman Standalone ZIP on your Windows PC.
2. Open PowerShell or Command Prompt and run:

   .\printman.exe share

3. That’s it! Printman broadcasts standard Apple AirPrint and Android Mopria discovery signals across your home Wi-Fi.

How to Print from iPhone / iPad:

1. Open any photo, email, PDF, or webpage.
2. Tap the Share button → Tap Print.
3. Select your USB printer from the list and tap Print.

How to Print from Android:

1. Open the document or photo.
2. Tap Menu (three dots) → Print (or Share → Print).
3. Select your printer discovered via Default Print Service or Mopria.
4. Tap the print button.

No OTG cable, no ad-heavy apps, and no cloud accounts.

Option B: Mobile Browser Drag & Drop (printman serve)

If you are on a restricted Wi-Fi network where discovery protocols are blocked, or you want to print from a guest device with a PIN-protected upload queue:

1. On your Windows PC, run:

   .\printman.exe serve

2. Printman displays a local LAN web address:

   [INFO] Web Server started at http://192.168.1.150:5000
   [INFO] PIN Authentication: 824192

3. On your phone, open Safari or Chrome and go to http://192.168.1.150:5000.
4. Enter the PIN, select your printer, drop your PDF or photo, and tap Print.
