selenium with geckodriver does not respect download dir and download filename when executing window.print();

Question

I have a set up where I print the page as pdf using selenium+gecko. But, whatever I do, it does not seem to respect the download.dir option I set nor the download filename.

Here are my settings:

        self.profile = webdriver.FirefoxProfile()
        self.headers = {'User-Agent' : uagent, \
                        'Accept' : 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', \
                        'Accept-Language' : 'en-gb,en;q=0.5', \
                        'Accept-Charset' : 'ISO-8859-1,utf-8;q=0.7,*;q=0.7', \
                        'Keep-Alive' : '115', \
                        'Connection' : 'keep-alive', \
                        'Cache-Control' : 'max-age=0'}
        self.profile.set_preference('browser.link.open_newwindow', 1)
        self.profile.set_preference("general.useragent.override", uagent)

        self.profile.set_preference("browser.download.manager.showWhenStarting", False)
        self.profile.set_preference("browser.download.dir", '/home/foo/')

        self.profile.set_preference("print_printer", "Mozilla Save to PDF")
        self.profile.set_preference("print.always_print_silent", True)
        self.profile.set_preference("print.show_print_progress", False)
        self.profile.set_preference('print.save_as_pdf.links.enabled', True)
        self.profile.set_preference("print.printer_Mozilla_Save_to_PDF.print_to_file", True)
        self.profile.set_preference("print.printer_Mozilla_Save_to_PDF.print_to_filename", "file.pdf")
        self.binary = FirefoxBinary('/path/to/Downloads/dir/firefox/firefox')

I have also tried:

        self.profile.set_preference("print.print_to_filename", "file.pdf")

To print I do:

        browser = webdriver.Firefox(firefox_profile=self.profile, \
                    firefox_binary=self.binary, executable_path='/some/path/dir/and/orm/driver/geckodriver')
        browser.execute_script("window.print();")

When I execute this I get the PDF in the directory I execute the script from and always as mozilla.pdf I am not sure what settings to use to change this.

I tried changing the page name to see if this will have any effect, but still, it prints out as mozilla.pdf

So yea, I am looking for a solution which can:

1. set the directory of the pdf
2. set the name of the pdf

:(

Answer 1

You were almost there. Once you have configured all the settings through set_preference(), finally you have to use update_preferences() as follows:

self.profile.update_preferences()

You can find a couple of relevant detailed discussions in:

To resolve, you need to include the path & filename as one.

• Below is using options, your example is using self, but the idea is the same!

important to note that printing will rasterize the PDF as an image, you cannot then highlight text...

url = '<__some_public_pdf_URL_here__>'

out_dir = './data/' # whatever your outdir is for the printed file
out_filename = 'file.pdf'
out_path = out_dir + out_filename

options = FirefoxOptions()

options.add_argument("--start-maximized")
options.set_preference("print.always_print_silent", True)
options.set_preference("print.printer_Mozilla_Save_to_PDF.print_to_file", True)
# this line should guarantee export to correct dir & filename
options.set_preference('print.printer_Mozilla_Save_to_PDF.print_to_filename', '{}'.format(out_path))

options.set_preference("print_printer", "Mozilla Save to PDF")

driver = webdriver.Firefox(options=options)

   try:
        driver.get(url)
        sleep(3) # give the browser a chance to load PDF
        driver.execute_script('window.print();')
        sleep(10) # give the PDF a chance to print, 10 seconds should be enough
        driver.close()
   except:
        print('oops! failed for {}'.format(url)
