设置Selenium ChromeDriver UserPreferences保存为

Question

我正在使用ChromeDriver2.33，并正在使用kiosk打印自动点击打印预览对话框上的打印按钮，但它将文档发送到打印机而不是PDF。

我尝试了这个堆栈溢出问题的解决方案，但没有成功。

ChromeOptions o = new ChromeOptions();
o.AddArgument("--kiosk-printing");
o.AddUserProfilePreference("printing.print_preview_sticky_settings.appState", "{\"version\":2,\"isGcpPromoDismissed\":false,\"selectedDestinationId\":\"Save as PDF\"");
chrome = new ChromeDriver(dir, o);

谁能告诉我如何将打印机从实际打印机设置为PDF？

Answer 1

尝试在recentdestinations上添加另存为PDF:

import json
settings = {
    "appState": {
        "recentDestinations": [{
            "id": "Save as PDF",
            "origin": "local"
        }],
        "selectedDestinationId": "Save as PDF",
        "version": 2
    }  
}
prefs = {'printing.print_preview_sticky_settings': json.dumps(settings)}
chrome_options = webdriver.ChromeOptions()
chrome_options.add_experimental_option('prefs', prefs)
chrome_options.add_argument('--kiosk-printing')

driver = webdriver.Chrome(chrome_options=chrome_options)
