[🐛 Bug]: Failed to get pdf file where setting the pref to headless

[loseangeltyj]

What happened?

I used selenium in chrome to output the pdf of the page.It works when not setting headless. But when I add the chrome_options.add_argument('--headless') # 无头模式 Its not working.No output

How can we reproduce the issue?

height_microns = 29700
    width_microns = 210000
    if page_type == 'A2':
