Silent Hawk C-100 Null Printer

With the C-100 Null Printer, host machines and data signals can be tested. Front panel switches on the unit allow busy, fault, paper empty, and select signals to be manipulated. This design permits the testing of the host machine and can help troubleshoot problems with the printer signals. The front panel LEDs of the unit display the last byte of data that was received by the null printer. With the LEDs, data is easily seen as it streams from the host machine to the null printer.
