A test scoring machine apparatus is used for grading and scoring test papers and printing the scores directly on each test paper. The printer includes a printer driver and a print head for printing on single sheets of paper passing through the computer printer. A cut sheet feeder is attached to the computer printer for feeding single sheets of paper from a stack of paper to the printer. A light source is attached to the printer in a position for directing light onto the surface of one test sheet being fed from the sheet feeder into the computer printer. An optical reader is attached to the computer printer adjacent to the light source for reading the reflected light being reflected off the test sheet so that marks on each test sheet being fed into the printer are read by the optical reader. A computer is attached to the printer and operatively coupled to the optical reader for receiving the output from the optical reader and producing an output signal analogous to a score from the signals read by the optical reader. A printer interface may be a parallel or serial interface and is coupled to the computer with a cable for driving the print driver to in turn drive the printer print head for printing a score on a test paper as it passes through the printer.
