    Using layouts
    1. Make a file, e.g. New_Layout.php
    2. Make a PDF class New_Layout_PDF extending FPDF
       (just copy an existing one to get the UPC/EAN/Barcode
        functions)
    3. Make a function New_Layout($data)
       Data is an array database rows containing:
        normal_price
        description
        brand
        units
        size
        sku
        pricePerUnit
        upc
        vendor
        scale
    4. In your function, build the PDF. Look at 
       existings ones for some hints and/or FPDF
       documentation

    Name matching is important
