Simple app

Hey!

I work in a store where we use a quite complicated TPV. My dad has really hard time with that software. I was thinking to make an simple app where he can input the name of the product, units, price. And can print it on a EPSON TM-T20II. Connected via USB. it not have bluetooth.

No need the data being saved in a database. When is printed the data is deleted.

Is that possible?

Cheers
