Hello, I have past experience of same kind of work. In my past project i used silent print without displaying the print dialog box on browser. Do u need same feature? This will require to use applet in browser and whenever user clicks on print it automatically goes to default printer configured in browser printing setup. Though one thing, what you mean by thermal printer?
PLEASE LET ME FURTHER AND WE WONT LET YOU DOWN.
Regards,
Mahesh.
