This converter may help if just the serial port on a personal computer is free, whereas the printer needs a parallel (Centronics) port. It converts a serial 2400 baud signal into a parallel signal.

In addition to series-to-parallel converters in digital electronic circuits, parallel-to-series converters are also needed. For example, 8-bit data generated in a circuit may need to be serialized and ...

This application note presents the process of converting a serial output into parallel output using common serial-to-parallel register integrated circuits. The document also discussed the CS556x/7x/8x ...
