Bi-directional switching supports two scenarios: two computers to one printer, or one computer to two printers. Two computers can share a printer without repeated plugging and unplugging, helping protect devices and reduce office costs. External controller support enables easier switching and control. Circuit safety protection includes overcurrent, reverse current, and short-circuit protection using printed circuit boards with embedded capacitors, resistors, and diodes. USB 3.0 interface enables fast file transfer for printing, with a theoretical transfer speed of up to 500 MB/s. File transfer performance is comparable to direct connection, improving office efficiency.
