What is it?

This app lets you change the text on an LCD display on any HP LaserJet printer! What could you do with this awesome power? You could send something funny to the LCD, like "Have a nice day," or "Hello," or "Goodbye." Or you could advertise a company event, like a birthday party or an open house. You could make the invitation, "Hey, everybody, come to my party! It's going to be great!"

How do you use it?

This app is very easy to use. Just download it, and install it on your phone. Then, when you want to use it, open the app and select the printer you want to use. You will be able to change the text on the display.
