      QPrinter::pageRect() returns different value before QPrinterDialog is shown to what it is after the printing. Setting the paper size before this makes no difference.

      The issue can be reproduced with the textedit demo by adding the following debug prints and paper size setting to TextEdit::filePrint() method

          QPrinter printer(QPrinter::HighResolution);
    printer.setPaperSize(QPrinter::A4);
    qDebug() << printer.pageRect(QPrinter::Millimeter);
    QPrintDialog *dlg = new QPrintDialog(&printer, this);
    if (textEdit->textCursor().hasSelection())
        dlg->addEnabledOption(QAbstractPrintDialog::PrintSelection);
    dlg->setWindowTitle(tr("Print Document"));
    if (dlg->exec() == QDialog::Accepted) {
        textEdit->print(&printer);
    }
    delete dlg;
    qDebug() << printer.pageRect(QPrinter::Millimeter);
