At each end of the hub section is a flange mounting rim comprised of two thin rim walls spaced apart the thickness of the flange material. Each outer rim wall has a rim notch. Each flange has an aperture including a notch corresponding to the notch on the flange mounting rim. The inner edge of the aperture adjacent to the notch is inserted into the rim notch of the mounting rim from one direction, and rotated in that same direction to mount the flanges within the rim.

The stand is provided with a shelf below the top surface for storage of paper which is to be printed, and provision is made for a slot in one or both side walls to feed the paper upwardly and outwardly into the printer. Each of the two side walls is generally planar and imperforate with the exception of the slots for the aforementioned paper feed. A basket may also be provided for reception of the paper after printing.
