UNIVERSAL COMPATIBILITY ensures seamless connection between devices equipped with DB25 female ports and peripherals featuring CN36 female connectors, supporting speeds up to 2MB/s for enhanced data transmission in both standard and EPP/ECP modes PROFESSIONAL GRADE CONSTRUCTION features 28 AWG premium copper conductors with 18 twisted pairs plus drain wire, engineered for superior signal integrity and reduced crosstalk in high-speed data transfer environments, ensuring reliable performance for mission-critical printing operations ADVANCED SHIELDING TECHNOLOGY incorporates dual-layer protection with aluminum foil and copper braid shields (85% coverage), effectively blocking EMI/RFI interference while maintaining IEEE-1284 compliance for seamless bi-directional communication Connect your PC with DB25 connector to printer, scanner or other IEEE-1284 compliant peripherals with CN36 connector. All relevant materials are complied with RoHS directive. To enjoy the increased data rate and two-way communication of your IEEE-1284-compliant printer or scanner, you need a cable with high quality connectors and a specialized wire type. This IEEE1284 bi-directional parallel printer cable connects computers with a DB25 female parallel port to IEEE-1284 compliant parallel printers with a Centronics 36 female parallel port. The cable supports high-speed IEEE 1284 bi-directional communication. Bi-directional communication allows your printer to broadcast printer error messages back to network computers. It is double shielded for maximum EMI/RFI protection.
