          previewDlg = new PrintPreviewDialog();
          PrintDocument pd = new PrintDocument();
          //Add print-page event handler
          pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
          pd.Print();
      }
public void pd_PrintPage(object sender, PrintPageEventArgs ev)
      {
          float x = ev.MarginBounds.Left - 50;
          float y = ev.MarginBounds.Top - 70;
          float pageheight = ev.MarginBounds.Height;
          Bitmap bmp = new Bitmap(this.pictureBox1.Width, this.pictureBox1.Height);
          int imgWidth=this.pictureBox1.Width;
          int imght = ev.MarginBounds.Height;
              this.pictureBox1.DrawToBitmap(bmp, new Rectangle(0, 0, imgWidth, imght));

C#

Bitmap myBitmap1 = new Bitmap(myPicturebox.Width, myPicturebox.Height);

Now Print this picturebox image.

myPicturebox.DrawToBitmap(myBitmap1, new Rectangle(0, 0, myPicturebox.Width, myPicturebox.Height));

e.Graphics.DrawImage(myBitmap1, 0, 0);
Then dispose the bitmap to release the resources.
Now create the objects of the PrintDocument & PrintDialog.
System.Drawing.Printing.PrintDocument myPrintDocument1 = new System.Drawing.Printing.PrintDocument();
PrintDialog myPrinDialog1 = new PrintDialog();
Now create the PagePrint event of PrintDocument

myPrintDocument1.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(myPrintDocument2_PrintPage);
Then assing the PrintDocument object to PrintDialog.

myPrinDialog1.Document = myPrintDocument1;
Finally it will print the Image which is in the picturebox.

if (myPrinDialog1.ShowDialog() == DialogResult.OK)
{
               myPrintDocument1.Print();
}
The above code will ask you the printer name in which you can print the picture.

The the full code for printing the picture.

private void myPrintDocument2_PrintPage(System.Object sender, System.Drawing.Printing.PrintPageEventArgs e)
        {
            Bitmap myBitmap1 = new Bitmap(myPicturebox.Width, myPicturebox.Height);
            myPicturebox.DrawToBitmap(myBitmap1, new Rectangle(0, 0, myPicturebox.Width, myPicturebox.Height));
            e.Graphics.DrawImage(myBitmap1, 0, 0);
            myBitmap1.Dispose();
        }
        private void btnPrintPicture_Click(object sender, EventArgs e)
        {
            System.Drawing.Printing.PrintDocument myPrintDocument1 = new System.Drawing.Printing.PrintDocument();
            PrintDialog myPrinDialog1 = new PrintDialog();
            myPrintDocument1.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(myPrintDocument2_PrintPage);
            myPrinDialog1.Document = myPrintDocument1;
 
            if (myPrinDialog1.ShowDialog() == DialogResult.OK)
            {
               myPrintDocument1.Print();
            }
        }
