How do I set the page orientation to landscape when rendering html to pdf using openhtmltopdf?

Question

I am trying to convert html to pdf using openhtmltopdf. I'm using mave openhtmltopdf.

Then I write the Main class (example below), but the problem is that I need the landscape orientation of the page and it was possible to adjust the font (now everything is moving out), what should I do for this?

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.nio.file.FileSystems;
import org.jsoup.Jsoup;
import org.jsoup.helper.W3CDom;
import org.jsoup.nodes.Document;
import com.openhtmltopdf.pdfboxout.PdfRendererBuilder;

public class Main {
    public static void main(String[] args) {
        try {
            // HTML file - Input
            File inputHTML = new File("D:\\Загрузки от 13.05\\htmltopdf\\4874063.html");
            // Converted PDF file - Output
            String outputPdf = "D:\\Загрузки от 13.05\\htmltopdf\\Test.pdf";
            Main htmlToPdf = new Main();
            //create well formed HTML
            org.w3c.dom.Document doc = htmlToPdf.createWellFormedHtml(inputHTML);
            System.out.println("Starting conversion to PDF...");
            htmlToPdf.xhtmlToPdf(doc, outputPdf);
        } catch (IOException e) {
            System.out.println("Error while converting HTML to PDF " + e.getMessage());
            e.printStackTrace();
        }
    }

    // Creating well formed document
    private org.w3c.dom.Document createWellFormedHtml(File inputHTML) throws IOException {
        Document document = Jsoup.parse(inputHTML, "UTF-8");
        document.outputSettings().syntax(Document.OutputSettings.Syntax.xml);
        System.out.println("HTML parsing done...");
        return new W3CDom().fromJsoup(document);
    }

    private void xhtmlToPdf(org.w3c.dom.Document doc, String outputPdf) throws IOException {
        // base URI to resolve future resources
        String baseUri = FileSystems.getDefault()
                .getPath("F:/", "Anshu/NetJs/Programs/", "src/main/resources/template")
                .toUri()
                .toString();
        OutputStream os = new FileOutputStream(outputPdf);
        PdfRendererBuilder builder = new PdfRendererBuilder();
        builder.withUri(outputPdf);
        builder.toStream(os);
        // add external font
        //builder.useFont(new File(getClass().getClassLoader().getResource("fonts/PRISTINA.ttf").getFile()), "PRISTINA");
        builder.withW3cDocument(doc, baseUri);
        builder.run();
        System.out.println("PDF creation completed");
        os.close();
    }
}```
