MediaSize 不适用于 Selenium Chrome 驱动程序 打印到 PDF
MediaSize does not work for Selenium Chrome driver Print to PDF
问：
我希望它以 A2 纸尺寸打印。但输出仍然是合法的。我尝试了其他纸张尺寸，但无济于事。
Python、Selenium 和 Chrome 是最新版本。
import json
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
url = 'file:///C:/Users/XYZ/Downloads/page_1.html'
# Set app state
app_state = {
"recentDestinations": [
{
"id": "Save as PDF",
"origin": "local",
"account": ""
}
],
"selectedDestinationId": "Save as PDF",
"isCssBackgroundEnabled": True,
"isHeaderFooterEnabled": False,
"isLandscapeEnabled": False,
"version": 2,
"mediaSize": {"height_microns": 594000, "width_microns": 420000}
}
profile = {'printing.print_preview_sticky_settings.appState':json.dumps(app_state)}
#STart
chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option('prefs', profile)
chrome_options.add_argument('--kiosk-printing')
driver = webdriver.Chrome(options=chrome_options)
driver.get(url)
time.sleep(2)
driver.execute_script('window.print();')
driver.quit()
替代版本也不起作用。"mediaSize": {"height_microns": 594000, "width_microns": 420000, "custom_display_name": "A2"}

您可以尝试使用这样的 pagesize 参数
import json
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import time
url = 'file:///C:/Users/XYZ/Downloads/page_1.html'
# Set app state
app_state = {
"recentDestinations": [
{
"id": "Save as PDF",
"origin": "local",
"account": ""
}
],
"selectedDestinationId": "Save as PDF",
"isCssBackgroundEnabled": True,
"isHeaderFooterEnabled": False,
"isLandscapeEnabled": False,
"version": 2,
"pageSize": "A2" # Set the pageSize directly
}
profile = {'printing.print_preview_sticky_settings.appState': json.dumps(app_state)}
chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option('prefs', profile)
chrome_options.add_argument('--kiosk-printing')
driver = webdriver.Chrome(options=chrome_options)
driver.get(url)
time.sleep(2)
driver.execute_script('window.print();')
driver.quit()
