My middle schooler often doesn't have more than a couple days between when he has everything necessary to complete an assignment, and when it is due. He has other workload, too, so there's no guarantee he's working on it that night. Getting to the one drugstore with a remaining photocenter near me in the evening is a pain. Even with notice, it's a pain.

People have legitimate reasons to want their own high quality color printers, even if that is its own pain, too.
