In my experience one of the costs that can very quickly get out of control with remote workers is the Copier/Printer/Scanner. It is very unusual for companies to have a strategy on these devices, so it usually ends up with the end-user purchasing a device and all of the consumables, which can be very expensive, and claiming them on expenses.

However, there are better ways of doing this, in a more controlled fashion, which I would be more than happy to share with anybody that is interested.
