title: Integrate USB POS printer with app from Android tablet
body: <p>My goal is to integrate a USB POS thermal printer with a small demo Android app that I will using from an Android tablet.</p>
  
  <p>I have two POS printers:</p>
  
  <ul>
  <li>Epson TM-T88III</li>
  <li>POS-5870</li>
  </ul>
  
  <p>I also have a Sanei N10 tablet that I am connecting to the POS printer via a USB OTG dongle cable.</p>
  
  <p>I downloaded the USB Host Diagnostic (from Google Play Store) to see if it would recognize the POS printers that I connected to the tablet. It recognized both printers, however the EPSON TM-T88III was recognized on the Android OS level while the POS-5870 was recognized only on the kernel level.</p>
  
  <p>I also tried using the USB Printer Driver 2.1 DevEd app (from the Google Play store), however I couldn't set the any of the printers as the default printer to use.</p>
  
  <p>I also tried using the POS Printer Driver (ESC) app (from the Google Play store), however, it couldn't connect with the printers.</p>
  
  <p>I was wondering if there is any way I can get the POS printers connected to my Android tablet and perform a test print? In addition, is there any SDKs/source code that I can use to detect and perform a test print?</p>
