USB printing in android tablet

[seethanellai]

Hi,

I am trying to print data using POS thermal printer. Currently i am able to print using ethernet and bluetooth.
Now i want to print to USB port. I have tried few things from google. Below are the suggestion got from google search.

1. Use QtSerialport.
   Qt provides QtSerialPort to talk with serial devices (no matter whether it’s a usb port or a real serial port)
2. http://www.libusb.org
3. Using java usbmanager

What could be the best option for usb printing from android tablet. Is there any other better options available other than above?

I guess third option is easiest to apply and it doesn't require root.
Also you may try with "Net2usb":https://play.google.com/store/apps/details?id=pl.iwkowalow.net2usb to avoid dealing with usb communication directly.
