title: Looking to write Simple Cash Register App, In over my head?
body: <p>My parents own a little pizza place, and they have been wanting to switch over to an electronic cash register with touch screen and a small printer for reciepts.</p>
  
  <p>They had one installed while I was away and I just saw it today. The one that they got is way too complicated for their needs. They are a small take out and delivery place but the software which they were given was made for a restuarant with tables and servers.</p>
  
  <p>I thought that I could write them an app in java (I'm a third year Comp-Sci student) to do what they needed. </p>
  
  <p>I'm wondering if I should attempt this or it is too much of a complicated task. What I think that it would need to have, is there products (sizes of pizzas/toppings/slices of pizza etc.) added in. It would also need to be able to print out reciepts for orders to a small printer, and open/close the cash till. </p>
  
  <p>EDIT: Also the things I am most scared about is handling the connection to a printer/cash till. Is this a hard thing to do?</p>
