Is it possible to use PhantomJS's rendering to PDF capabilities when PhantomJS is being used in combination with Selenium and Python? (ie. mimic page.render('file.pdf') behaviour inside Python via Selenium).

I realize that this uses GhostDriver, and GhostDriver doesn't really support much in the way of printing.

If another alternative is possible that isn't Selenium, I'm all ears.

Here is a solution using selenium and special command for GhostDriver (it should work since GhostDriver 1.1.0 and PhantomJS 1.9.6, tested with PhantomJS 1.9.8):

#!/usr/bin/env python

# -*- coding: utf-8 -*-

"""Download a webpage as a PDF."""

from selenium import webdriver

def download(driver, target_path):

    """Download the currently displayed page to target_path."""

    def execute(script, args):


                       {'script': script, 'args': args);

    # hack while the python interface lags

    driver.command_executor._commands['executePhantomScript'] = ('POST', '/session/$sessionId/phantom/execute'

   # set page format

    # inside the execution script, webpage is "this"

    page_format = 'this.paperSize = {format: "A4", orientation: "portrait" };'

    execute(page_format, [])

    # render current page

    render = '''this.render("{}")'''.format(target_path)

    execute(render, [])

if __name__ == '__main__':

    driver = webdriver.PhantomJS('phantomjs')


    download(driver, "save_me.pdf")
