Your code will never print to a PDF document as there are no references made to the PDF libraries, what it will do is in summary, your 'printTable' method opens a new browser window, copies the HTML content of your table with the 'id 'mytable'' to that window, and then prints the content of that return -

a Full explanation of what your function does -
1) It retrieves an HTML table element with the id 'mytable' using 'document.getElementById('mytable')' and stores it in your variable 'tab'.
2) It opens a new browser window using 'window.open('', '', 'height=700,width=700')'. The parameters passed to 'window.open' are used to specify the height and width of your new window.
3) It then writes the HTML content of your table 'tab.outerHTML' to the document of the newly opened window using 'win.document.write(tab.outerHTML)'.
4) It then closes the document of that new window using 'win.document.close()'.
5) It then triggers the print dialog for the new window using 'win.print()' - No PDF involved anywhere.
