主题：急！老大，条码打印不行，应是代码问题？

 

Dim doc As New PrintDoc
Dim rbc As New prt.RenderBarCode()
rbc.Width = 60
rbc.Height = 20
rbc.BarCodeType = BarCodeEnum.Code39
rbc.BarDirection = BarDirectionEnum.Normal
rbc.Text = "123456"
rbc.ShowText = True
doc.Body.Children.Add(rbc)
Doc.Preview()

打印预览效果，直线有阴影，打印出来是点线或波浪费，有的是直线。请老大帮看看，急！！
