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 ...

[Fernando] wrote in to share his take on building a logic analyzer. He’s using the parallel port to capture data and feed it to the display software of your choice. The method depends on a custom ...

This 66-year-old precursor to USB refuses to become obsolete ...

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.

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 ...

(1) A hardware interface that transfers one or more bytes simultaneously. See parallel interface. (2) A socket on a computer used to connect a printer or other device via a parallel interface (eight ...

I have a PC-based DSO that connects via parallel port that I'd like to get working via USB (preferable) or at least ExpressCard. I picked up a USB-parallel adapter from MicroCenter thinking it would ...

[Vinod] sent in a very cool build he says is somewhat of a ‘mad project’: he mounted an MMC and SD card under Linux using the parallel port on his computer. Even though parallel ports are getting ...

Parallel port access changed significantly between Win95 and WinNT - in '95 it was possible for user programs to directly twiddle parallel port bits but NT made that impossible (only a driver can ...

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 ...
