Print in ionic1 using thermal printer via bluetooth

Hi Guys

I am trying to print order from thermal printer via bluetooth in ionic1 and I just want to by pass print preview option and print direct on click on print button.

Please help me in find the way to print.

I want the printing app like POS PRINTER DRIVER ESC/POS

I also tried to implement this but ad ( POS PRINTER DRIVER’s title ) is showing on top of print receipt and I want to get rid of this.
