Share USB peripherals between two computers to improve office efficiency. Compatible with a wide range of USB devices. Intelligent control with a performance main control chip delivers smooth, reliable switching and broad compatibility, enhancing work efficiency. Two computers can share a single printer. Forget about plugging and unplugging when switching print tasks, which protects equipment and reduces office costs. No external power supply is required. The printing port operates normally without an external power source. Use scenario 1: In a small office with two PCs that need access to a single printer and common USB devices, enabling seamless switching and reducing cable clutter. Use scenario 2: In a shared design studio or lab where two workstations need to alternate printing tasks and access USB peripherals, improving workflow and reducing wear on ports. Use scenario 3: In a home office with two computers used for different tasks, allowing centralized USB resources and easy device sharing without extra power or setup.
