How do I get this code to print multiple pages?

public void invoicePostingReportPrintReportButton_Click(object sender, EventArgs e)
{
    if (invoicemainresults == null)
    {
        MessageBox.Show("You must create a report before you can print it");
        invoicePostingReportStartDateTimePicker.Focus();
        return;
    }
    else
    {
        foreach (var result in invoicemainresults)
        {
            _sProNumber += result.ProNumber + Environment.NewLine + Environment.NewLine;
            _sLoadNumber += result.LoadNumber + Environment.NewLine + Environment.NewLine;
            _sShipmentNumber += result.ShipmentNumber + Environment.NewLine + Environment.NewLine;

        }
    }
