Javascript print function uses the printer on browser instead

Question

For some reason using

    var sample = "test";
    print(sample);

the print function doesn't print the string on the web browser , however it literally uses the print function on my chrome browser . any idea why ? Im actually learning javascript from http://eloquentjavascript.net/ and it uses the print function too.

The window.print() method opens the print dialog to print the current document, Not part of any standard. ( from MDN )

If you want to print something in your page, use document.write() function. The text you write is parsed into the document's structure model

if you want to print something for simple debugging purpose, use console.log() , which prints the output in browsers console. read more at MDN - console.log()
