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 ...

With the continuing manufacture of new computers, there is a clear and obvious trend of the parallel port becoming less and less common. For our younger readers; the parallel port is an interface ...

If your small business is typical, you want to get the longest lifespan possible from your tech investment, and therefore you may have an older dot-matrix or laser printer with a parallel port that ...

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 ...

*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 ...

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 ...

The 24-bit I/O card project has been designed to function with parallel/printer port of an Amiga or computer using the Intel 82C55 I/O chip. The design of the device contains read & write strobe, a ...

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 ...

The circuit shown in Figure 1 steals energy from a PC's parallel port or from any limited-energy source. To use the available energy, such power-conversion applications usually require very high ...

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 ...
