Print Preview/Printing artifacts

Unfortunately, there is no way to optimize the look for the gauge labels; however, as a workaround, you could export the gauge to a memory stream, and draw the image directly to the Print Object in the PrintPage() Event using GDI+. You could provide a button in your application for PrintPreview, for example, which will fire this PrintPage() event thus showing the gauge image with much better quality. Below, please find a code snippet on how to implement this solution:

public partial class _Default : System.Web.UI.Page


private MemoryStream ms;protected void Page_Load(object sender, EventArgs e)


ms = new MemoryStream();

RadialGauge1.MainValue = 75;

RadialGauge1.MainScale.Min = 0;

RadialGauge1.MainScale.MinAlwaysDisplayed = true;

RadialGauge1.MainScale.Max = 100;

RadialGauge1.MainScale.MaxAlwaysDisplayed =

true;RadialGauge1.Export(ImageFormat.Jpeg, ms);

ms.Position = 0;

PrintDocument pd = new PrintDocument();

pd.PrintPage +=

new PrintPageEventHandler(pd_PrintPage);System.Windows.Forms.PrintPreviewDialog ppd = new System.Windows.Forms.PrintPreviewDialog();

ppd.Document = pd;



void pd_PrintPage(object sender, PrintPageEventArgs e)


e.Graphics.DrawImage(System.Drawing.Image.FromStream(ms), new Point(25, 25));
