I need a pos machine which has an API for .NET. I have a Verifone vx 680 and I contacted their help desk and asked about their supporting APIs. They wrote me
They are not. You'll need to purchase a Developer's Package, and attend a training session first. Information on this process can be found here: http://www.verifonedevnet.com/verifone/jsp/devnet/account/dnGetCertified.jsp
So, for using that API, I have to buy some package.
What I need is some kind of a printer/pos which can print like this
Customers will push buttons and then I will print those numbers. However, I must be able to print these numbers via computer. In other words, I must control this printer with my program and I will be able to see which numbers printed. At the close of the day, everything must be restarted (that is, counting starts from "one" on each day)
I searched zebra printers' support APIs for .NET, but I am also looking for for a cheaper one. I don't need a developed device because it will just print some numbers to order.
There is no api, you need to develop your own verifone POS application to create a communication between your Verifone 680 and your .NET desktop application.
