Hello, I have interfaced a centronics dot matrix printer with the 8051 controller. I am able to print the text on it. Now I have a application in which I have to print a graph using its graphics mode on to it. How can we print a graph using the dot matrix printer through a microcontroller. Also, what is the ASCII code for the form feed (FF) character? Regards, Mohit
That's very unhelpful of them - giving you an incomplete ASCII table! It's impossible to drive a printer without knowing all those "device-control" code like CR, ESC, FF, etc.
Don't you have an ASCII table at hands? Don't worry, there's a lof of tables online on the web... http://www.asciitable.com/
