C # Use the BarcodeControl bar code control to generate a bar code. How can I minimize the size of the generated bar code, because the printing process is too large, which wastes paper <div>
<Barcode: BarcodeImage ID = "bar1" runat = "server" BarcodeType = "CODE128B" CopyRightText = "" Data = "S014S037-20130513" Height = "80px" Width = "200px"/>
</Div>

Detune the height and width
C # Winfrom QRcode QR code printing. I know how to print a single bar code when the bar code is connected. But I don't know how to write it in bulk. help me write it on CSDN.
The font of the barcode is enough.
