Like title say, is it possible accessing PC device such as printer, scanner, customer display and others device (POS peripheral) connected to client PC from browser ?
We all know webapp will run at server-side
Let assume every device has successfully connected and map to its USB/COM port, how our B4J webapp directly communicate with them ?
A remote server has very limited access to clients computers.
The browser can access some features with the right permissions. You can then use JavaScript to send data back to the server.
