Ultimate Guide on TP-LINK Archer C2 AC750 Wireless Dual Band Gigabit Router - USB Printer sharing on OS X

This guideline should be applying to any USB compatible printer for sharing on OS X over the USB port of TP-LINK Archer C2 Wireless Router.

The best thing of this router is that it's NBN ready and has both WAN/LAN ports supporting up to 1000Mbps which is abundant for movie streaming and VOIP communications within local network and a possible extension to future upgrade of NBN services. As for 802.11ac standard, this router does the right job for 5GHz Wi-fi transfer which is up to 433Mbps. It's also backward compatible with 802.11b/g/n. The cost is average but you might feel good about having an 802.11ac compliant router with this price tag. Compared with my old 802.11n router, it really makes a difference in terms of the speed and stability. One benefit is beamforming if you are using newer Macbook with antenna supporting 802.11ac standard.

Now you can proceed to plug the USB printer into the USB port of TP-LINK Wireless Router for remote setup.

The software TP-LINK USB Printer Controller will let you to bridge up the remote printer to your local USB printer profile. It may show offline at first but will turn into online mode after the first remote printing is done successfully.
