Xerox released the DocuTech Production Publisher Model 135

Development of digital photocopiers in the 1990s and a revamp of the entire product range again gave Xerox a technical lead over its competitors. In 1990, Xerox released the DocuTech Production Publisher Model 135, ushering in print-on-demand. Digital photocopiers were essentially high-end laser printers with integrated scanners. Soon, additional features such as network printing and faxing were added to many models, known as Multi-Function Machines, or just MFMs, which were able to be attached to computer networks. Xerox worked to turn its product into a service, providing a complete document service to companies including supply, maintenance, configuration, and user support.
