Printing JavaScript Output

Question: How do I print JavaScript output?

Answer: JavaScript programs cannot directly access printers. However, the user can print out everything on the Web page, including the output of JavaScript programs, by using the File | Print menu of the browser (or the keyboard shortcut, e.g. Ctrl+P on Windows systems).

If your script outputs data that users would often print out, then just remind them to use the File | Print menu. Also, your script might generate the printable data in a separate browser window (see example below).

Example. This script generates the multiplication table, writes it to a new browser window and explains to the user how to print it.
