我是做前端的，(lll￢ω￢)！！！，由于.net的工程师离职，遗留下来一个问题，就是wpf打印条形码的时候，出现锯齿的现象。
我也不清楚如何解决，请教wpf的大神，帮忙看下！！！小弟感激不尽。打印机是TSC的

下面是.xmal里面的内容，打印的主要内容：

 <Grid>
        <Grid Name="grdLabel" Width="840" Height="260" >
            <Grid.RowDefinitions>
                <RowDefinition Height="0*" />
                <RowDefinition Height="23*" />
                <RowDefinition Height="2*" />
                <RowDefinition Height="5*" />
                <RowDefinition Height="4*" />
                <RowDefinition Height="5*" />
                <RowDefinition Height="5*" />
                <RowDefinition Height="5*" />
                <RowDefinition Height="6*" />
            </Grid.RowDefinitions>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="0*"/>
                <ColumnDefinition Width="33*"/>
                <ColumnDefinition Width="51*"/>
            </Grid.ColumnDefinitions>

            <Image Grid.Row="1" Grid.Column="1"  Name="imgSN" HorizontalAlignment="Left" Stretch="Uniform" UseLayoutRounding="False"/>
            <StackPanel Orientation="Horizontal" Grid.Row="4" Grid.Column="1" Margin="15,0,0,0">
                <TextBlock Margin="1,0,0,0" FontSize="18" VerticalAlignment="Bottom" Text="产品序列号:" Grid.Column="1" FontWeight="Bold"/>
                <TextBlock Name="tbLabelSN" FontSize="18" VerticalAlignment="Bottom" Grid.Column="1" FontWeight="Bold"/>
            </StackPanel>
            <StackPanel Orientation="Horizontal" Grid.Row="5" Grid.Column="1" Margin="15,0,0,0">
                <TextBlock FontSize="18" VerticalAlignment="Bottom" Text="颜色:" Grid.Column="1" FontWeight="Bold"/>
                <TextBlock FontSize="18" VerticalAlignment="Bottom" Text="{Binding Path=Model.Color.Color,Mode=OneWay}" Grid.Column="3" FontWeight="Bold"/>
            </StackPanel>
            <StackPanel Orientation="Horizontal" Grid.Row="6" Grid.Column="1" Margin="15,0,0,0">

                <TextBlock FontSize="18" VerticalAlignment="Top" Text="{Binding Path=Model.Name,Mode=OneWay}" Grid.Column="1" FontWeight="Bold"/>

            </StackPanel>
            <StackPanel Orientation="Horizontal" Grid.Row="7" Grid.Column="1" Margin="15,0,0,0">
                <TextBlock FontSize="18" VerticalAlignment="Top" HorizontalAlignment="Right" Text="生产日期:" Grid.Column="2" FontWeight="Bold"/>

            </StackPanel>
        </Grid>

下面是打印标签的代码：

             void PrintLabel(string sn)
    {
        System.Drawing.Bitmap m_Bitmap = new System.Drawing.Bitmap(Elecnode.GeneratorBarcode(sn),276*6,94*6);
        //m_Bitmap.Save("./lalalala.png");
        //m_Bitmap.Save("./nidayue.png");
        IntPtr ip = m_Bitmap.GetHbitmap();
        BitmapSource bitmapSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
            ip, IntPtr.Zero, Int32Rect.Empty,
            System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());


        DeleteObject(ip);
        imgSN.Source = bitmapSource;
        tbLabelSN.Text = sn;
        grdLabel.UpdateLayout();

        PrintDialog printDialog = new System.Windows.Controls.PrintDialog();
        //var renderTarget = new RenderTargetBitmap((int)grdLabel.Width, (int)grdLabel.Height, 600, 600, PixelFormats.Default);

        var renderTarget = new RenderTargetBitmap(940, 260, 310, 320, PixelFormats.Default);
        renderTarget.SetValue(RenderOptions.BitmapScalingModeProperty, BitmapScalingMode.NearestNeighbor);
        printDialog.PrintTicket = new PrintTicket();
        printDialog.PrintTicket.PageMediaSize = new PageMediaSize(renderTarget.Width, renderTarget.Height);
        var capabilities = printDialog.PrintQueue.GetPrintCapabilities(printDialog.PrintTicket);//0.33502812148481437  0.31995154451847363  0.1599030890369473
        var scale = Math.Max(capabilities.PageImageableArea.ExtentWidth / grdLabel.Width, capabilities.PageImageableArea.ExtentHeight / grdLabel.Height);
        grdLabel.LayoutTransform = new ScaleTransform(scale, scale);
        var sz = new Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight);
        grdLabel.Measure(sz);
        grdLabel.Arrange(new Rect(new Point(0, 0), sz));

        printDialog.PrintVisual(grdLabel, "标签打印");

        //isFirstPrint = false;
    }
