I wish I had one of these on my desk when I was in school, but better late than never! Designed to fit standard thermal paper for retail receipt pri ters, rolls 8 cm long, 7 cm in diameter.

First, feed the paper through the base plate, slide the rod through the base plate and paper roll, and start writing! I had no problem writing on it with standard settings, but if you would like a smoother surface consider enabling ironing on the top layer.
