Hi Mohit,

The easy bit first - 0Ch shold throw a page.

For the graphics characters, you will need to study carefully the printer's manual. It's a bit of work to establish what to print for a graph, but once you've decided that there are X values across & Y values down, it should start to be clear. My usual advice - make it work on paper first! A good place to start for this is to create a bmp image (64x64 pixels is OK), study its file in hex/binary & try to print it via your own conversion routine.

Good luck!
