如何禁用页眉和页脚打印

Question

有人知道如何在使用selenium打印时禁用“页眉和页脚”选项吗？默认设置为true，有人知道如何修复吗？谢谢你

import json
import os
from selenium import webdriver

# setting html path
htmlPath = os.getcwd() + "\\sample.html"
addr = "file:///" + htmlPath

# setting Chrome Driver
chromeOpt = webdriver.ChromeOptions()
appState = {
   "recentDestinations": [
        {
            "id": "Save as PDF",
            "origin": "local",
            "account": ""
        }
    ],
    "selectedDestinationId": "Save as PDF",
    "version": 2
}
prefs = {
    'printing.print_preview_sticky_settings.appState': json.dumps(appState)}
chromeOpt.add_experimental_option('prefs', prefs)
chromeOpt.add_argument('--kiosk-printing')
driver = webdriver.Chrome('.\\bin\\chromedriver', options=chromeOpt)

# HTML open and print
driver.get(addr)
driver.execute_script('return window.print()')```

只需将"isHeaderFooterEnabled": False添加到appstate下面的更改中即可

appState = {
   "recentDestinations": [
        {
            "id": "Save as PDF",
            "origin": "local",
            "account": ""
        }
    ],
    "selectedDestinationId": "Save as PDF",
    "version": 2,
    "isHeaderFooterEnabled": False
}

屏幕截图：注释了chromeOpt.add_argument(' kiosk-printing')行，只是为了在屏幕截图中显示取消选中的选项。
