The USB-Parallel Printer Cable allows PCs, notebooks, laptops, and handheld computing 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-n-play and hot-plugging capability - in which the cable is automatically detected by Windows. For further convenience - especially to users of notebooks, laptops, and handhelds - the cable 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.
