"High-speed IEEE-1284 compliant cables from Cables To Go ensure you realize the added speed and two way communications offered by your newer inkjet, laser, or all-in one printers and scanners. This advanced technology, which defines high-speed, bi-directional communications between PC and peripheral, requires both high quality connectors and a specialized wire-type to handle the increased data rates. Seventeen pair wire twisted with at least 36 turns per meter, molded connectors, foil shielding and 85% coverage braid soldered 360 degrees to the connector shell- providing maximum resistance against harmful EMI/RFI and achieving the maximum performance for your peripheral. Connectors: DB25 Male (A) to Centronics 36 Male (B). Provides increased speed and functionality over standard parallel cabling. Greater protection against EMI/RFI interference. Maximum end-to-end attenuation not to exceed 1.5 dB at 5Mhz. Works with IEEE-1284 compliant inkjet, laser, all-in one printers and scanners and other IEEE-1284 compliant peripherals."
