I can't print...

[brevleq]

I'm having a problem to print a QTextDocument!!
When I set the "print to file" checkbox in QPrintDialog, no problem! The file is correctly saved in disk, but when I try print, this message appears in konsole:

QPainter::begin(): Returned false

This the method I'm using to print:

void Visualizador::imprimir(void){
	defDocumento();
	QPrintDialog telaImprimir(&printer,this);
	if(telaImprimir.exec()){
		QPainter painter(&printer);
		relatorio.print(&printer);
	}
}

void Visualizador::imprimir(void){
	defDocumento();
	QPrintDialog telaImprimir(&printer,this);
	if(telaImprimir.exec()){
		QPainter painter(&printer);
		relatorio.print(&printer);
	}
}

To copy to clipboard, switch view to plain text mode 

The var relatorio is a QTextDocument and the text was setted in defDocumento()!
