At a time when computers first started to occupy the classrooms and offices, there was the concept of "paperless" office. It was assumed that all the office work will be computerized so that all documents will be only exist in digital form and the need for paper simply disappear. Projections were too ambitious in view of the fact that "hard" paper (hard copy) is easier to work. First, clearly presented information, and secondly, to its perception does not require special devices. Thus, the apparently "solid" media will not disappear from the office ever. At the moment there most of the tools and ways of displaying information in writing: copiers, printers, fax machines. Naturally, all these devices the same brand of paper can not be used.
Such an approach would be very wasteful, or (if you only use expensive and good paper), or lead to damage or shorten the life of appliances (if takes on cheap and not good quality paper, which, however, is also wasteful, since the repair "will fly a lot of money"). For any technology for image if we consider the ideal option requires its own paper, is characterized by a certain set of parameters. Paper for copiers Bending and humidity. Being in the "womb" copier very short time, sheet, moreover, subject to rigorous "testing." Walking around the drum, the feed rollers and other parts of the conveyor mechanism, it bends and, if the moisture content was much too high, stuck. Under the influence of high temperatures and pressures characteristic for the processes of image formation, wet paper may curl.
