Besides saving lots of paper, this will also save a lot of money for the parents.
I'm really tired of paying outrageous prices for printer ink and enriching executives who I believe should be in Jail instead. Free market systems are supposed to have competition to keep prices reasonable. Instead these thugs first sell printers below cost which in itself is a very dubious action. On top of that they have made it very hard to use refilled cartridges since many printers complain and misbehave with refilled cartridges. Also cartridges that used to carry 15-20ml of ink now only carry 5ml or less of ink. To add insult to injury, the caridges are over packaged to make them look bigger and add more trash to the landfill. Its outrageous that this kind of behaviour is legal. Don't these people have a conscience?
The least we can do is reduce our usage and if teachers could allow emailed documents, ink and paper costs would not be wasted. emailed documents are also easy to store and organize. No reason to print homework.
