Save Printer Page Settings to show on next print

[arunkumaraymuo1]

I am trying to save a page settings of a printer for future use in my application

I tried this bot not worked because m_printer is not a variant type its the object QPrinter

objVar= m_settings.value("PrinterSettings", m_printer);
    m_printer = objVar.value<QPrinter>();

objVar= m_settings.value("PrinterSettings", m_printer);
    m_printer = objVar.value<QPrinter>();

To copy to clipboard, switch view to plain text mode 

m_settings.setValue("PrinterSettings", m_printer);

m_settings.setValue("PrinterSettings", m_printer);

To copy to clipboard, switch view to plain text mode 

How to save printer settings and re asign to next time use

You must retrieve each of the page settings you are interested in and save them individually:

QSettings settings( "MyOrg", "MyApp" );
settings.setValue( "PaperSize", m_printer.paperSize() );
settings.setValue( "ColorMode", m_printer.colorMode() );
// etc.
 
m_printer.setPaperSize( QPrinter::PaperSize( settings.value( "PaperSize" ).toInt() ) );
m_printer.setColorMode( QPrinter::ColorMode( settings.value( "ColorMode" ).toInt() ) );
// etc.

QSettings settings( "MyOrg", "MyApp" );
settings.setValue( "PaperSize", m_printer.paperSize() );
settings.setValue( "ColorMode", m_printer.colorMode() );
// etc.

m_printer.setPaperSize( QPrinter::PaperSize( settings.value( "PaperSize" ).toInt() ) );
m_printer.setColorMode( QPrinter::ColorMode( settings.value( "ColorMode" ).toInt() ) );
// etc.

To copy to clipboard, switch view to plain text mode 

Basically, you can't convert a QPrinter instance into a QVariant for use in setValue(). So, you must store each setting separately, with type conversions as appropriate.
