JxBrowser comvert html to pdf with 7.X release

Question

I want to convert an html file to pdf using TeamDev jxbrowser. I want to trigger it automatically wihout any extra print dialog or popup etc just by executing some code. And I also want to set some extra settings. In the 6.X versions I can see more detailed options by coding

https://jxbrowser.support.teamdev.com/support/solutions/articles/9000013120-print-settings

browser.setPrintHandler(new PrintHandler() {
            @Override
            public PrintStatus onPrint(PrintJob printJob) {
                PrintSettings printSettings = printJob.getPrintSettings();
                printSettings.setLandscape(true);

But in 7.x relases there are very few details for customizing pdf generation step by code.

• Is it not possible with newer releases getting a PrintSettings instance?
• Can we set custom header and footer content?

Answer 1

The Printing API that allows programmatically printing the currently loaded web page using the PDF printer is not available in JxBrowser 7. It's already on our roadmap. We do our best to introduce this functionality in one of the next versions.

I recommend that you follow us on https://twitter.com/JxBrowserTeam to be notified when this functionality is released.

UPD: In JxBrowser 7.13 the Printing API has been extended with functionality that allows programmatically configure print settings and print a web page without displaying the Print Preview dialog. The API allows you to save the currently loaded web page as a PDF document. Read more at https://jxbrowser-support.teamdev.com/docs/guides/printing.html#configuring-settings

The following example demonstrates how to save a web page as PDF:

import static com.teamdev.jxbrowser.engine.RenderingMode.OFF_SCREEN;
import static com.teamdev.jxbrowser.print.Orientation.PORTRAIT;

import com.teamdev.jxbrowser.browser.Browser;
import com.teamdev.jxbrowser.browser.callback.PrintCallback;
import com.teamdev.jxbrowser.browser.callback.PrintHtmlCallback;
import com.teamdev.jxbrowser.engine.Engine;
import com.teamdev.jxbrowser.frame.Frame;
import com.teamdev.jxbrowser.print.PdfPrinter;
import com.teamdev.jxbrowser.print.PdfPrinter.HtmlSettings;
import com.teamdev.jxbrowser.print.PrintJob;
import com.teamdev.jxbrowser.print.event.PrintCompleted;
import java.nio.file.Paths;
