For portable-sensing and data- acquisition applications, a laptop computer and its parallel port (LPT) make good bedfellows. Yet in the effort to extend battery life, many microprocessors and entire ...

A parallel port, which is standard equipment on nearly every IBM-compatible PC, can be connected directly to TTL/CMOS circuits. The standard parallel port provides 12 logic outputs and five inputs.

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 ...

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 ...

PLIP (Parallel Line Internet Protocol) is simply a protocol to link two computers point to point through a PC parallel port, through which it exchanges IP datagrams. It is not a standard protocol; you ...

Right now DAGU is in the prototype stage, but already there are some really interesting features: the interface allows for a basic preview of the job before it begins, and should be somewhat ...

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 ...

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 ...
