Error in printing a form - forms

Question

Hi guys I've got an error in this.printPreviewDialog1 (the project no contains a definition for printviewdialog and no extension for printviewdialog accepting a first argument of type Project print. I already added up the reference System.Printing and System.Windows.Form.Data Visualization. What I miss? Thanks
public partial class Print : Form
{
public Print()
{
InitializeComponent();
this.button1.Click += button1_Click;
this.printDocument1.PrintPage += printDocument1_PrintPage;
}
private void Print_Load(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
this.printPreviewDialog1.Document = this.printDocument1;
this.printPreviewDialog1.Document.DocumentName = "PictureTextDesignerFile1";
this.printPreviewDialog1.Size = new Size(800, 600);
this.printPreviewDialog1.ShowDialog();
}
private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{

this.DrawToBitmap(bmpPrint, new Rectangle(0, 0, bmpPrint.Width, bmpPrint.Height));

e.Graphics.DrawImage(bmpPrint, e.MarginBounds.Left, e.MarginBounds.Top, Math.Min(neededWidth * zoom, availableWidth), Math.Min(neededHeight * zoom, availableHeight));
