Mobile development

I need an Android app. I would like it designed and built. I have a simple web application hosted on my server. I have purchased a Bluetooth Thermal Printer. The printer comes with its own android SDK and a sample program. I am looking for a way I can print from the web directly to the Thermal Printer using chrome on android. I am able to create an output in text to print, but want a solution of what is the best way to print from Chrome (android) to the printer. The freelancer is expected to suggest a solution to this including the necessary programming for the solution. I wish to use my existing web application and not any new android application. Need some connectivity using SDK so that printing can be done from Chrome to Bluetooth thermal printer.
