FEATURE

OVERVIEW

The PL-2305 USB-to-IEEE-1284 Bridge Controller is a low-cost high-performance single chip solution that

provides bi-directional connectivity between any standard IEEE-1284 compliant parallel port devices and the

Universal Serial Bus (USB) interface. Software drivers for Microsoft Windows 98 and NT 5.0 are also

provided to create a seamless migration path from traditional parallel port to the USB environment.

The PL-2305 is based on Prolific Technology’s USB Universal Parallel Bridge Controller (U-PBC)

Dual-Thread Micro-Controller. With 512 bytes of unified data buffer, it is capable of providing maximum

throughput for both upstream and downstream data transfer for a wide variety of devices. The IEEE-1284

interface of PL-2305 is robust enough to handle various not-so-compliant parallel port implementations.
