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 ...

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 ...

Parallel port access changed significantly between Win95 and WinNT - in '95 it was possible for user programs to directly twiddle parallel port bits but NT made that impossible (only a driver can ...

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 ...

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 ...

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 ...

Anyone know? I wanted to get something semi-rugged for a friends CNC setup, or at least something that's easy to get a skin for the keyboard. Thinkpad stuff is usually easier to find. I suppose a ...

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 ...

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 ...
