Fun With C# and HP Laserjets
Cool code to hack your HP Laserjet to display little messages on the LCD.
"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?"
