wxMathPlot & printer

[Anonymous]

Hello everyone
I have a little problem with wxMathPlot.
I can't understand (but is still due to my lack of knowledge of wx libraries) because when I print a graphics the texts become very small and the grid very dense.
I think it's due to the resolution of the printer and the same problem also occurs with the examples that are given in support of wxMathPlot.
How can I change my code so that the chart is printed in the same way (roughly) how it is displayed on the screen?

void AnalisiFrame::OnPreview( wxCommandEvent& event )
{
    // Pass two printout objects: for preview, and possible printing.
    mpPrintout *plotPrint = new mpPrintout(m_plot);
    mpPrintout *plotPrintPreview = new mpPrintout(m_plot);
    wxPrintPreview *preview = new wxPrintPreview(plotPrintPreview, plotPrint);
    wxPreviewFrame *frame = new wxPreviewFrame(preview, this, wxT("Print Plot"), wxPoint(100, 100), wxSize(600, 650));
    frame->Centre(wxBOTH);
    frame->Initialize();
    frame->Show(true);
}
void AnalisiFrame::OnPrint( wxCommandEvent& event )
{
    wxPrinter printer;
    mpPrintout printout(m_plot, wxT("Plot print"));
    printer.Print(this, &printout, true);
}

Thanks in advance.

This is my program to work.
For the moment I only implemented the rescue of the curves in a graphical format for the printing problem I reported previously.
