Key benefits Share one USB device between two computers to increase office efficiency and reduce downtime. Eliminate repeated plugging and unplugging when switching printers or other USB devices, protecting ports and extending equipment life. No external power required: the printer port operates normally without an additional power supply, simplifying setup and reducing costs. Durable construction with a black ABS case that resists drops and wear for reliable daily use. What it does Allows two computers to share USB peripherals (for example printers, scanners, external drives, or other USB devices) without swapping cables. Provides a simple hardware switch point so devices remain connected and ready to use from either computer. Key attributes Function: Share USB devices and a printer between two computers. Compatibility: Suitable for a variety of USB devices; works with two computers that need to access the same USB peripheral. Material: Sturdy black ABS housing that resists falling and wear. Power: No external power supply required; the printing port works normally without additional power. Performance: Reduces wear on devices and cabling by eliminating frequent plug/unplug cycles and lowers office operating costs. Practical use scenarios Small office: Two workstations share a single printer so staff can switch printing jobs without unplugging cables, protecting printer and PC ports and saving time. Home office: A desktop and a laptop can both access the same external drive or scanner without moving cables, making file transfers and scanning more convenient. Classroom or lab: Multiple computers take turns using a single USB peripheral (scanner, label printer, or camera) while the device stays connected and protected. How it helps you Saves time and simplifies device access across two computers. Protects hardware from repeated plugging and unplugging. Lowers equipment maintenance and replacement costs. Durable design built for regular use in office and home environments.
