The Hawking UC1284P USB to Parallel Printer Adapter allows your PCs, notebooks, laptops, and handheld PDA devices that support the USB specification to print to any parallel printer via the USB with up to 12 Mbps throughput - which is much faster than standard parallel port speeds. The cable provides true Plug and Play, as well as hot plugging capabilities. For further convenience, the adapter derives its operating power from the Universal Serial Bus itself, so no bulky external power supply needs to be taken along. And because it is a USB Specification compliant device, the cable supports energy-saving "suspend" and "resume" operations.
