Hi Shaoxiong,

Browsers are very security conscious about allowing access to system hardware and ports.  They do not allow web pages to do it. 

You ave two options.  You can use the print driver by calling window.print().  The other option is to write a small app to run on the OS that acts as an intermediary taking javascript calls and outputting to the serial port.
