A manually operable tablet splitting device, including a base and a cover, pivotally attached to the base, and movable between a tablet loading position and a tablet splitting position. The all-optical demultiplexer is implemented in either a semiconductor hybrid or in a completely monolithic form. When the amount of received data for which the accumulated data information has been stored in the data file exceeds one page worth, then n-pages worth of received data is converted into print data and recorded in a print FIFO. The arm is movable relative to the belt to position the contact device against the belt to provide tension on the belt.
