PC using a type connector, socket DB-25 pass, including 17 signal lines and 8 line, signal lines are divided into 3 groups, control line 4, status line 5, data line 8. The printer uses a type-B connector, which is a 085inch pitch Champ connector of 36PIN, called the

parallel port popular in electronics hobbyist world. the parallel port is often used in computer controlled robots, Atmel/PIC programmers, Home Automation ,... etc... here is a simple tutorial on parallel port interfacing and programming, with some examples. Everybody knows what is parallel port, where it can be found, and for what it is being used. the primary use of parallel port is to connect printers to the computer and is specifically designed for this purpose. thus it is often called as p

along the cables through each device and eventually into the computer. using this method, the devices can even communicate with each other. the original SCSI standard allowed you to string up to seven devices together, while the newer standards allow daisy-chaining of up to 15 devices. Because the signal passes through each device in the chain, the chain must be terminated at the end to prevent signal bounce (an echo that interferes with the original signal's clarity, causing interference and

data transmission standard (IRDA) is a mechanism for information exchange between computers using infrared transmission without cable connections. IRDA can be performed between any two devices (such as computers and printers) that support IRDA. Windows 2003 supports IrDA printing. IRDA is a Point-to-Point Protocol Based on TCP/IP and Winsock APIs (application programming interfaces. Generally, the IrDA printer supports out-of-the-box use. If the corresponding driver is available on the workstat

MCU and can be saved as a text file, the information area holds the network working state, the command of the remote PC, and the data transmission of the single-chip microcomputer. Its working process is shown in Figure 2 (c). 3 local PC and MCU communication design 3.1 Local PC and single chip computer communication design 3.1.1 Parallel communication Interface and protocol In the case of higher rate requirements, you can use the PC printer interface (

Computer hardware, including all the physical parts of the computer, to differentiate the data it includes or perform and the software that provides instructions to the hardware to accomplish the task, what are the main products of the computer hardware? Computer hardware mainly includes: chassis, motherboard, bus, power supply, storage controller, interface card, carrying device, internal memory, input device, output device, CPU fan, buzzer and so on. The motherboard includes: The motherboard
