How to print current opened page as PDF file?

[yuis]

Hello.

I'm using selenium webdriver on Ruby.

I want to print PDF file on chrome on selenium.

But I have two problems.

1. There is no way to click "print" button automatically. JavaScript not works.

2. My Windows PC connecting with some printers. In printing page on chrome on selenium, default selecting printing method is not a PDF but the printer.

How do I do it?

example

```

chrome --headless --disable-gpu --print-to-pdf https://www.chromestatus.com/

```

If i am not mistaken it uses CDP

under the hood but is used simply as a process with arguments
