Parallel cable is the cable for computers defined by the IEEE 1284 standard for connecting peripherals via the parallel port. It is often used for connecting printers compatible PC computers. It is considered an outdated connection and has been replaced by USB. – IEEE 1284 Type A: 25-pin DB-25 IEEE 1284 – IEEE 1284 Type B: 36 Drivers, Champ type Centerline Connector 0.085 insurance (Centronics). – IEEE 1284 Type C: 36 conductors, connector type mini Champ de Centerline 0.050 with secure clip (mini Centronics).
The Centronics 36-pin Centronics 36-pin connector is arranged in two rows of terminals, each with 18 contacts. It has fastening clamps. Centronics connector 36 is typically used for connecting printers normally. Also can be called IEEE 1284 Micro Centronics 36-pin Micro Centronics connector has two rows of pins, each row has 18 contacts. This connector has clampsclamping. It is very similar to Centronics 36-pin connector but half his size. Can also be called IEEE 1284 Type C connector, this connector is mainly used for multi-function devices. The Centronics 50-pinCentronics 50-pin connector has two rows of pins, each row has 25 contacts. This connector has clamps. The Centronics 50-pin connector is the utilizADO SCSI-1 (scanners, hard drives) devices. A variation Centronics connector 50 used in voice applications, this variant is called Telco connector.
English stands for Enhanced Parallel Port serious. It is a communication method for bi-directional parallel between the PC and peripherals, offering speed ratios and much higher than traditional transfer methods for parallel transfer. EPP is not for printers, however ECP is mainly for printers and scanners. It is part of the IEEE 1284 standard.
SPP correspond to Standard Parallel Port. It belongs to the IEEE 1284 protocol and serves to create a Bidirectional Parallel Peripheral Interface for PCs. It is a protocol that is compatible with all PC devices unlike ECP and EPP.
