The HP Printer Display Hack article has been posted to the Coding4Fun site. This is an article and application that I wrote that lets you display a stock price on the display panel of an HP (or compatible) laser printer.
The app is written in C# with WPF and it periodically checks the current price of your favorite stock and sends a PJL command to the printer to put that price on the display. It comes with a Windows Installer, written with WiX.
You can read the article at Coding4Fun. The source code and a precompiled installer are up on CodePlex, I would like to thank Brian Peek for letting me
steal borrow some of the TweeVo code for the UI bits.
