-- 关于条码打印的问题
想打印条码 采用了专业报表的方式设计了标签，
但是直接打出来条码有锯齿，但是转换成PDF的话 打印出来的还是很清晰的，
专业报表里面可以有办法改善这方面的问题么，因为不想通过生成PDF的方式手动点选打印
此主题相关图片如下：上为打印报表打印下为pdf.jpg

那在请教一下老师 这个功能我怎样做能将条形码添加在之前绘制的指定表格art.Cells(2,0)里，
我这直接加的话 会变成两页标签
Dim ccc As New prt.RenderGraphics()
Dim BarID1 As New BarCodeBuilder
BarID1.Symbology = Barpro.Symbology.Code128
BarID1.Code = ID111
BarID1.QuietZoneWidth = 3
BarID1.DrawOnCanvas(ccc.Graphics,0,0,1)
