Removing borders when printing an image

printing

I am trying to print an image using a labelprinter. I created the image but when I print it, a page border of like 1 cm is placed around the image which means half my label is empty. How can I disable these borders and sent the raw image to the printer?

As my label printer can operate as a normal windows printer I am using it like that. I want to create a windows print job to print the image.

namespace PrintSample 
{ 
public partial class PrintForm : Form 
{ 
private System.IO.Stream streamToPrint; string streamType;

    public PrintForm()
    {
        InitializeComponent();
    }

    [System.Runtime.InteropServices.DllImportAttribute("gdi32.dll")]
    private static extern bool BitBlt
    (
        IntPtr hdcDest, // handle to destination DC
        int nXDest, // x-coord of destination upper-left corner
        int nYDest, // y-coord of destination upper-left corner
        int nWidth, // width of destination rectangle
        int nHeight, // height of destination rectangle
        IntPtr hdcSrc, // handle to source DC
        int nXSrc, // x-coordinate of source upper-left corner
        int nYSrc, // y-coordinate of source upper-left corner
        System.Int32 dwRop // raster operation code
    );

    private void printDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        System.Drawing.Image image = System.Drawing.Image.FromStream(this.streamToPrint);
        int x = e.MarginBounds.X;
        int y = e.MarginBounds.Y;
        int width = image.Width;
        int height = image.Height;
        if ((width / e.MarginBounds.Width) > (height / e.MarginBounds.Height))
        {
            width = e.MarginBounds.Width;
            height = image.Height * e.MarginBounds.Width / image.Width;
        }
        else
        {
            height = e.MarginBounds.Height;
            width = image.Width * e.MarginBounds.Height / image.Height;
        }
        System.Drawing.Rectangle destRect = new System.Drawing.Rectangle(x, y, width, height);
        e.Graphics.DrawImage(image, destRect, 0, 0, image.Width, image.Height, System.Drawing.GraphicsUnit.Pixel);
    }

    public void StartPrint(Stream streamToPrint, string streamType)
    {
        this.printDoc.PrintPage += new PrintPageEventHandler(printDoc_PrintPage);
        this.streamToPrint = streamToPrint;
        this.streamType = streamType;            
        System.Windows.Forms.PrintDialog PrintDialog1 = new PrintDialog();
        PrintDialog1.AllowSomePages = true;
        PrintDialog1.ShowHelp = true;
        PrintDialog1.Document = printDoc;

        DialogResult result = PrintDialog1.ShowDialog();
        if (result == DialogResult.OK)
        {
            printDoc.Print();
        }

    }

    private void btnPrint_Click(object sender, EventArgs e)
    {
        FileStream fileStream = new FileStream(@"c:\PrintPage.jpg", FileMode.Open, FileAccess.Read);
        PaperSize.Equals(1, 1.5);
        StartPrint(fileStream, "Image");
        fileStream.Close();

    }
}
