Retractable Printer spans out according to the paper size

Since my company is an Engineering company, I had to choose a high capacity larger printer for my office. That network printer supports almost all the paper sizes. But what really my problem is that it consumes relatively larger space. Designer Neilson Navarrete designed this Retractable Printer concept to overcome such issues. This creative design can span out according to the paper size you print. But, designer hasn't mention anything about the paper capacity and how we gonna keep those papers inside the tray. Further, will it suitable for a larger buzy organizations? What would be the ink expense?
