Don’t ask me why, but i’ve always been fascinated about label printing, especially when it comes with a barcode. Yes, i actually own a barcode scanner which is collecting dust somewhere. Anyway, barcodes were designed to relieve the need for human data entry (and hence reduce human error as well), which is why they are popular for Point-of-Sales applications. It may be the impression of many that it costs a lot of money to print these complicated looking barcoded labels, but it could actually be done for free (using a standard laser/inkjet printer and adhesive label sheets).
