This article may require cleanup to meet the Qt Wiki's quality standards. Reason: No print support on mobile platform (iOS), different issues on different targets
Please improve this article if you can. Remove the {{cleanup}} tag and add this page to Updated pages list after it's clean.

Here is a minimal example of how to print a QTextDocument to PDF:

#include <QtWidgets>
#ifndef QT_NO_PRINTER
#include <QPrinter>
#endif

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    QString fileName = QFileDialog::getSaveFileName((QWidget* )0, "Export PDF", QString(), "*.pdf");
    if (QFileInfo(fileName).suffix().isEmpty()) { fileName.append(".pdf"); }

    QPrinter printer(QPrinter::PrinterResolution);
    printer.setOutputFormat(QPrinter::PdfFormat);
    printer.setPaperSize(QPrinter::A4);
    printer.setOutputFileName(fileName);

    QTextDocument doc;
    doc.setHtml("<h1>Hello, World!</h1>\n<p>Lorem ipsum dolor sit amet, consectitur adipisci elit.</p>");
    doc.setPageSize(printer.pageRect().size()); // This is necessary if you want to hide the page number
    doc.print(&printer);
}
