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 ...

FM synthesis is the sound of the 1980s, it’s the sound of shopping malls and Macintosh Plus. It’s the sound of the Motorola DynaTAC, busts of Helios, and the sound of vaporwaveサ閲ユ. The chips most ...

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 ...

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 ...

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 ...

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 ...

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 ...

Despite the rise of ARM processors in more and more computers from embedded systems to daily driver PCs, the x86 architecture maintains a stronghold in the computing space that won’t be going away ...
