Fun With C# and HP Laserjets

`I was studying the C# language one day and thought back to earlier in my career. Back then I was learning the assembly language for a little 8 bit Hitachi CPU (the 6303) in order to control a small thermal printer. With the right control codes you could get the printer to display a custom message on the LCD. Then I was walking by the HP Laser printer in the office and wondered if I could do the same here. Once I uncovered the Printer Job Language Reference from HP, I realized this could be fun. After all, who would not get a kick out of a printer with the message TOUCH ME on the LCD?’

With source code. I might give this a try, just for fun. 🙂
