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.

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 ...

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 ...

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 ...

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

High-resolution temperature sensing at low cost is possible using only one chip attached to the PC's parallel port (Figure 1). The Dallas Semiconductor (www.dalsemi.com) DS1722 digital thermometer ...

*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 ...

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 ...

For PCI bus interfacing, the OX16PC1952 brings together a PCI interface, two high performance serial channels, and a parallel port in one compact, 128-pin TQFP package. This integrated bridge device ...

The mode chosen by the software driver is based on the connected device. 1-Compatibility mode supports the Centronics interface at 150 KB/sec. 2-Nibble mode supports Bi-tronics; HP's parallel port ...

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 ...
