主题：请教关于条码打印效果的问题

现在有个条码打印需求，参照例子做了个实例。

 

要达到的效果：

此主题相关图片如下：22.png

 

 

实例代码： 

Dim value As String  = e.Form.Controls("start").value
Dim n As Integer = e.Form.Controls("No").value
Dim strN As Integer = Cint(Value.Replace("2121030928DAE5",""))
Dim str As String
Dim i As Integer
    For i  = 0 To StrN + n -2
        str = "2121030928DAE5" &  Format(strN + i,"000000")
        Dim doc As New PrintDoc
        Doc.PageSetting.Landscape = False
        Doc.PageSetting.LeftMargin = 1
        Doc.PageSetting.TopMargin = 2.5
        Doc.PageSetting.BottomMargin = 2
        Doc.PageSetting.RightMargin = 1
       
        Doc.PageSetting.Width = 60
        Doc.PageSetting.Height = 15
        Dim bar As new  BarCodeBuilder
        Dim img As new  prt.RenderImage
        bar.Symbology  = Barpro.Symbology.Code128
        bar.DisplayCode = True
        bar.Code = str
        bar.Text = "B" & " " & Date.Today()
        Bar.CodeAlignment = Barpro.Alignment.BelowLeft
        Bar.TextAlignment = Barpro.Alignment.BelowRight
        img.Image = bar.GetImage
        Doc.Body.Children.Add(img)
        Doc.Print()
    Next

 

 测试预览效果还满好样，打印结果就不行了，如图：

请教下，怎样能调整到能达到预期效果呢。

微调一下,以打印为准,不要管预览.

像这情况，一般调哪几个参数比较靠谱。

 

Doc.PageSetting.LeftMargin = 1
        Doc.PageSetting.TopMargin = 2.5

 除了位置，你的条码设置得也不是很对，看这里，调好了条码，再拷贝代码进去
