Parallel to USB Adapter: Connect USB printer to LPT port US$119.00

Parallel to USB Adapter: Connect USB printer to LPT port

Adapter to connect the parallel LPT port of computers to the USB port of printers.

This 1.8m adapter cable has a male 25-pin Sub-D connector to connect to the parallel port (LPT) on computers on one end and a USB-B connector to connect to the USB port of printers on the other end. It requires no drivers or software, and converts the SPP, ECP, IEEE1284 and IEEE1284.4 printing protocols to USB. The adapter also supports the bi-directional Nibble Mode, Byte Mode, ECP–Reverse and BECP-Reverse modes.

This adapter allows you to replace your old printer without having to replace your established system. Use it to connect modern printers and multifunction printers that have a USB connection to the LPT interface of legacy PCs, measuring devices, laboratory and diagnostic devices, control panels, medical devices as well as all other products that were designed with a parallel printer interface. Note however that only printing is supported.

The adapter cable comes with its own 100-240V, 50/60Hz power supply with interchangeable U.S., UK and European power plugs.
