title: How do you generate small, high-density linear barcodes that scan reliably?
body: <p>I am working to integrate POS system to my site. So I want to generate barcode. I am using SKU as the data fields to encode the formate is <code>XXXXX-XXX-XXX-XXX</code>. </p>
  
  <p>X is a digit from 0 to 9 so after doing research I found code 128 is the best correct me if I am wrong. The problem with size, The label on items are 2' by 3 1/2' inches, when I generate barcode using <code>barbecue</code> and resize the image the scanner cannot read the barcode. So could you please explain what is the size constrains and what is the smallest size that I can get in inches. </p>
