The kinematics seems harder but the material handling of paper, ink jets, and laser fusing process are all difficult compared to an extruder and require pretty specialized parts.
Aside from making a pen plotter, it would be very difficult to make an open source 2D printer. A 3D printer is an enabler of this, but I would think to be feasible you would have to at least find a popular "business end" of the printer to reuse. There is a project called "openprinter" that is attempting to make an open source inkjet printer but it's really early days.
