ABOUT HP Display Changer
With HP Display Changer, changing the message on HP printers is now possible from your mobile phone! Great for office jokes, could also be used to relay an important message such as a meeting.
This application is only meant to work on HP printers, mostly LaserJet although it has been known to occasionally work on some other brands of printers including Kyocera.
Unlike any other app on the play store you have the ability to change the regular display message as well as display an error message, although be forewarned an error message will stop the printer from being able to print until someone clicks OK on the printer itself. An error message will also disappear when the person presses OK.

If you run into any problems restarting the printer should always clear any messages.
Warning this may get you in trouble if you do not own the printer you use it on. It is not my responsibility if you do have problems or find yourself in trouble. HP is not affiliated with this app in any way what so ever.
