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 ...

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 ...

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.

*sigh*<BR><BR>So here's what the problem is. Part of my job requires me to reconfigure laser bar code scanners and recalibrate them in order to read a bar code at different speeds and angles. In order ...

Text LCD’s are handy for any occasion, a printer port on your PC is also darn handy as well. Mix together and add in a splash of linux and you get a very handy Linux device driver for a 16×2 LCD ...

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 ...

In the olden days, plugging something into your computer—a mouse, a printer, a hard drive—required a zoo of cables. Maybe you needed a PS/2 connector or a serial port, the Apple Desktop Bus, or a DIN ...

Supporting both IEEE1284-I and -II bi-directional parallel communications between personal computers and peripherals, the 74LVC161284TTR and 74LVCZ161284ATTR parallel-port transceivers can each ...

While doing my usual surfing routine today, I came across an interesting read over at CNET. Some creative artists have made their mark in the oddest of places, a microchip. Some of the designs are ...

I'd probably get a USB to serial (RS-232) adapter and then stick a serial to parallel adapter on the end of it. Long time ago I bought a USB to parallel port adapter cable to use with an old HP laser ...

You don’t need fancy ICs and DACs to build a sound card for a PC. As [serdef]’s build over on hackaday.io shows, all you really need is a bunch of resistors. [serdef] built a clone of a sound card ...
