INSTALLATION INSTRUCTIONS:

  USB port technlogy has emerged in response to the proliferation of extermal  peripheral devices (scanners,digital cameras,

removable drives,etc.).that are increasingly being connected to

the latest generation of PCs.USB behaves in a  similar fashion to conventional bus ports (i.e.,serial,parallel, PS/2),but  since it

does not require any IRQs,more devices can be attached to the 

system,and the problem of  IRQ computing devices that support the USB specification to any parallel printer via the USB with up to 12Mbps 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.
