I would also find this useful.
I am about to replace an old cash register with SambaPOS running on an old laptop with a USB reciept printer and cash drawer, and some form of touch screen.
I will probably end up buying the printer, drawer and screen from Amazon.
If anyone can post here what they are using, or a link to a list that would be very helpful as I am going to make a decision in the next few days.
In any case, I will post details of what I buy and if it works here.
Thanks in advance.
