I have a lot to write on papers that I grade. So the most common errors that I find I type out a response to the student. Ex. Capitalize beginning words in a sentence and then I just stick them on the paper and because I use the clear product the student in still able to read what they wrote. It saves me a lot of writing.
There is not much to say about address labels other than they did the job and I liked the ease of adjusting the printe to accept the labels i.e. comparing to brands the printers list.
