Printing without QPrintDialog (not on default printer)

[addebito]

Hi,
there is a way to print a page on a specific printer without the user interaction?

I have 2 printers:
Canon XXXX
DYMO LabelWriter 450 <-- this is the default printer

Now I'd like to print on a Canon XXXX directly by code and without to show the QPrintDialog.
How can I do that?

I can iterate on QPrinterInfo list... but it doesn't return a QPrinter object.

  QList<QPrinterInfo> plist = QPrinterInfo::availablePrinters();
  qDebug() << "numbers of printers:" << plist.length();
  foreach (QPrinterInfo pinfo, plist) 
  {
    qDebug() << "printer name:" << pinfo.printerName();
  }

https://doc.qt.io/qt-5/qprinter.html#QPrinter-1 constructor takes a QPrinterInfo, which is what you have in your QPrinterInfo::availablePrinters() list.

Oh my god, it was so easy...

    QString printerName       = "Canon XXXX";
    QList<QPrinterInfo> plist = QPrinterInfo::availablePrinters();
    foreach (QPrinterInfo pinfo, plist)
    {
        qDebug() << "printer name:" << pinfo.printerName();
        if (printerName.compare(pinfo.printerName()) == 0)
        {
            QPrinter printer(pinfo);
            m_report->printReport(&printer);
            break;
        }
    }

Thank you so much @JonB

Even simpler: you don't need to do the search yourself :) Just use static QPrinterInfo QPrinterInfo::printerInfo(const QString &printerName), https://doc.qt.io/qt-5/qprinterinfo.html#printerInfo !

    QString printerName = "Canon XXXX";
    QPrinterInfo pinfo  = QPrinterInfo::printerInfo(printerName);
    if (!pinfo.isNull())
    {
        QPrinter printer(pinfo);
        m_report->printReport(&printer);
    }
    else
    {
        // show user message: printer not found...
    }

Thanks again @JonB
