Will a specifically formulated toner be needed? How much will that cost, AND, how much will we be charged (two different things) ? What sort of pollutants will be produced by evaporating it into a relatively closed office (or home) ? How much power per sheet will it require, and how will that compare to the cost per sheet of buying new paper? How much time/effort will be needed to process paper for re-use?
I can envision some relatively closed environments where this concept could make sense, such as regenerating internally-used reference materials, work orders, and other documentation; where it can all be collected and centrally erased for re-use, but in general it looks like trying to use a kitchen knife as a screwdriver (or a screwdriver as a kitchen knife).
