C#

create a project of type "Windows Forms"

And you added the tool "WebBrowser"

And I want to save the open web site inside the tool "WebBrowser" Via a printer "Microsoft Print to PDF"

Provided that the process is silent

And the code displayed is actually saving silently

But how do I give it a command to print the displayed website with a tool "WebBrowser"

// generate a file name as the current date/time in unix timestamp format
string file = (DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds.ToString();

// the directory to store the output.
string directory = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);




// initialize PrintDocument object
PrintDocument doc = new PrintDocument()
{

    PrinterSettings = new PrinterSettings()
    {
        // set the printer to 'Microsoft Print to PDF'
        PrinterName = "Microsoft Print to PDF",

        // tell the object this document will print to file
        PrintToFile = true,

        // set the filename to whatever you like (full path)
        PrintFileName = Path.Combine(directory, file + ".pdf"),


    }
};

doc.Print();
