First I want to know if is possible to such thing.
I'm developing a web application where the user has to print receipts on their own thermal printer.
I don't want to use Java applet or Flash on client as with the entry of html5 these technology are going to be not supported by browsers. So I want to do this using PHP on server side, JavaScript on client browser if is possible.
If only JavaScript isn't enough what kind of application should I develop to install on client so it will help the JavaScript to accomplish is duty. I need some information and references how I can reach this objective. (Please No Microsoft technologies for the client app... Java, Python, NodeJs are welcome)
Thanks in advance
