being useless to you doesn't mean its useless for others.
Imagine this being used in convention centers, where one could print the daily schedule on a sheet of paper that was reused from a previous convention.
This used in mass to handle today's sermon and lyrics to the churchgoers, and then have the flyer be reused on the next day for a different sermon.
This used internally in companies to share confidential information among employees.
This used in hospitals, to print the information of a short-term patient.
There are plenty of uses. You are just thinking about your needs.
