Answer 1

I have created POS scanning barcode in magento invoice. It's very simple and easy to customize for single product or invoice number.

Edit : app\\code\\local\\Mage\\Sales\\Model\\Order\\Pdf\\Invoice.php

$fontPath = 'fonts/code39.TTF';                                
$barcodeImage = "*".$pro_sku."*";
$page->setFont(Zend_Pdf_Font::fontWithPath($fontPath), 36);

//Draw image to PDF
$page->drawText($barcodeImage, 400, 800);

POS easy to scan code39 fonts.
