This library is for driving VFDs (vacuum fluorescent displays) based on the Mitsubishi/Renesas M66004 VFD controller IC. This includes the display/control panel used in many HP LaserJet printers such as the LaserJet 4 series. Usage of the library is quite similar to the standard LiquidCrystal library.
Also included is a class and sample for using the buttons on LEDs on the LaserJet board.

The library and examples are available here: M66004Vfd.zip
See Arduino Libraries for information on how to install libraries. For the purposes of that page, this library is a "user-created library".
