I have a big problem ;)!!Yan can maybe help me.

Exemple

@void MainWindow::openprinterconfig()
{

   QPrintDialog *dialog = new QPrintDialog(myprinter);

   dialog->exec&#40;&#41; ;
   qDebug("%f", myprinter->paperRect(QPrinter::Millimeter).height());
   qDebug("%f", myprinter->paperRect(QPrinter::Millimeter).width());
   qDebug(myprinter->printerName().toLocal8Bit());

}@

case 1:Dymo is default printer and i try to select BROTHER printer
31.750000
57.150000
Brother HL-2140

case 2:BROTHER is default printer and i try to select Dymo printer

with this code
QPrintDialog *dialog = new QPrintDialog(this);
@ if(dialog->exec() ==QDialog::Accepted)

   {
        QPrinter* printer3 = dialog->printer()  ;
        qDebug(dialog->printer()->printerName().toLocal8Bit());
        printer3->setFullPage(true);
        qDebug("%f", printer3->pageRect(QPrinter::Millimeter).height());
        qDebug("%f", printer3->pageRect(QPrinter::Millimeter).width());
    }@

QT return:

if the BROTHER is the default printer:
DYMO LabelWriter 450
297.000000
210.000000

if the DYMO is the default printer:
DYMO LabelWriter 450
31.750000
57.150000

Pretty strange indeed. What version of Qt/OS are you running ? What compiler are you using ?
