Parallel port output ePanorama
This Data Register is simply used for outputting data on the Parallel Port's data lines (Pins 2 9). If your port is bi directional, you can receive data on this address.Parallel Port Breakout board with Buffer for CNC & Routers ...
Parallel port I O break out board designed for Hobby CNC, Routers and Motion controller , This Board is an easy solution to driver stepper Motor driver, AC Servo (with Step DIR Driver) and DC servo (with Step DIR Driver), The Board is compatible with various CNC software specially made for LPT port data out.Parallel Port, Lamp Faders, RF Transmitters
Parallel Port Relay Interface. Below are three examples of controlling a relay from the PC's parallel printer port (LPT1 or LPT2). Figure A shows a solid state relay controlled by one of the parallel port data lines (D0 D7) using a 300 ohm resistor and 5 volt power source.Controlling Stepper Motor with a Parallel Port

The Parallella computer is a high performance, credit card sized computer based on the Epiphany multi core chips from Adapteva. The Parallella can be used as a standalone computer, an embedded device or as a component in a scaled out parallel server cluster.Get power out of PC RS 232 port ePanorama.net
Addition 05 2004: There are better regulators chip for this application than the 7805. For example the LM2931 from National Semiconductor has a very low voltage drop and a very low quiescent current.DI DO Port D Link Forums
The DI DO port schematic is available in DCS 2132L user's manual (on page 77 in the version I have). DO usage is very simple, you can connect e.g. relay to these output pins to drive isolated AC loads.
the parallel port schematic is shown below the serial port schematic Gallery
