Hi
http://doc.qt.io/qt-5/printing.html

   QPrinter printer;
    printer.setOutputFormat(QPrinter::PdfFormat); 
    printer.setOutputFileName("/my.pdf");
    QPainter painter;
    QFont font=painter.font() ;
    font.setPointSize ( 64 ); /// BIIG
    painter.setFont(font);
    painter.drawText(10, 10, "Test 2");
    painter.end();

Hi Mrjj,

How can print the Bigger size on "paper", the code posted by you will print in the PDF File.
How can i get the data into String so that i can print..!

Thanks in advance,

@Rohith There is no difference. Just use a real printer instead of PDF. See http://doc.qt.io/qt-5/qprinter.html#setPrinterName
How do you actually print now?
