Printers.
As soon as the first personal computers appeared, someone came to think that all these computerized data could determine the order of the paperwork in the office. We are more than a decade the emergence of PCs and millions of trees continue to be felled for the production of paper copies of various things, from budgets to complex business color images for cards party and thanks. Not only the number of printed materials is increasing every day as printing became exquisite. The real purpose of this new category of programs - it is named after publishing electronic (desktop publishing) - is nothing more than the pursuit of printed pages getting better.
Whoever made the wrong prediction about the free office papers, forgot one important detail.
This person certainly was thinking about as wasted paper at the time of the typewriter. In reality, there

The color became the main frontier to be conquered by current printers. The quality and speed of printers
Color is increasing and decreasing cost. Like the black and white printers are becoming increasingly rapid and
more accessible, a complete replacement for color models will take, but these are becoming increasingly
common in networked offices, which can be shared.
And the paper has not disappeared from escrtitório. Instead, it is acquiring new importance. And the printer was modestly
