Any peripheral component can be controlled by the 25-pin parallel port by assigning a high & low or ON & OFF state to each pin. During the design of the project, a Super Nintendo Entertainment System ...

The project illustrates how an inexpensive logic analyzer is made to connect with a PC using the parallel port. The project illustrates how an inexpensive logic analyzer is made to connect with a PC ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc needs ...

If you’ve ever looked into low-level parallel port access you may have learned that it only works with actual parallel port hardware, and not with USB parallel port adapters. But here’s a solution ...

If you want to talk to a typewriter using something other than your fingers on the keys, you could do a lot worse than to pick up a specimen featuring a Centronics parallel port. That’s what happened ...

For portable-sensing and data- acquisition applications, a laptop computer and its parallel port (LPT) make good bedfellows. Yet in the effort to extend battery life, many microprocessors and entire ...

Many laser printers last for years, so businesses often keep older laser printers around even after upgrading other hardware. Many older laser printers use a parallel port interface rather than the ...

First introduced in 1970, parallel ports were originally designed to connect business computers to printers. With their inclusion on the IBM PC in the early 1980s, they became an industry standard.

This design modifies a simple first-order, low-pass filter into a slewing-voltage control that is programmable for its slope and amplitude through a PC's LPT port. These control parameters are ...
