print.print_paper_width doesn't works
I have been trying to print the webpage as PDF. I am trying to change the page height and width, but this code is not working. When I manually enter the value of print.print_paper_width and save in about:config it works. Can someone tell me whats wrong. This is what I am trying:
from selenium.webdriver.firefox.options import Options as FirefoxOptions
from selenium import webdriver
options = FirefoxOptions()
options.add_argument("--headless")
FFprofile = webdriver.FirefoxProfile()
FFprofile.set_preference('print.always_print_silent', True)
FFprofile.set_preference('print.print_to_file', True)
FFprofile.set_preference('print.print_paper_width', '3.7')
FFprofile.set_preference('print.print_to_filename', 'filepath')
driver = webdriver.Firefox(FFprofile,options=options) driver.get('filepath') driver.execute_script("window.print()")

This is a forum to support Firefox end users so not really the best place to get help on this. I can possibly help though if you can file an issue at https://bugzilla.mozilla.org/ in the 'Core' product and in the 'Printing: Setup' component. The Firefox core code for handling settings is currently in flux, and this use case is probably even more broken in the Firefox 82/83 code. We can try to make this work though.
