将 Selenium ChromeDriver UserPreferences 设置为另存为 PDF [英] Set Selenium ChromeDriver UserPreferences to Save as PDF

问题描述

我正在使用 ChromeDriver 2.33 并且正在使用自助服务终端打印来自动单击打印预览"对话框上的打印"按钮，但是它将文档而不是 PDF 发送到打印机.

I am using ChromeDriver 2.33 and am using kiosk printing to automatically click the Print button on the Print Preview dialog however it is sending the document to the printer instead of PDF.

我在 这个堆栈溢出问题无济于事.

这是我正在使用的代码:

Here is the code I am using:

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?

Can anyone tell me how I set the printer to PDF from the actual printer?

推荐答案

尝试在 recentDestinations 上添加 Save as 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)
