POS - Point of Sale ALL-IN-ONE

I am interested in updating... Currently, I am using a cash register and handwriting every ticket... I am interested in getting a POS that will print up the ticket, exactly how I my pizza guy wants it to be.

I also what Online ordering that will either fax me the order, or auto print it to my machine, with some form of notification system to let me know that I have a pending order.

Any suggestions?

Thank you in advance.
