One of the charms of the Point Of Sale business is that it is dominated by small companies. Of course, companies like IBM and Epson produce POS hardware, but both companies have set up very specialized departments that work separated from the rest of the company. Don’t try to find drivers for Epson receipt printers on www.epson.com; you’ll have to look at the site of the Epson SD group. In the POS software market, the presence of the big guys is even less prominent. Microsoft does have POS software, but they hardly sell it outside the USA.
