No worries at all. We aren't trained on perpherals so you may need to seek help from Samsung as its their printer but the basic are this:
1. Make sure your printer has network capablities
2. Make sure your router's WPS feature is enabled. You can do this by going to TP-Link.com searching for your router's model and reviewing the User Guide.
3. Press WPS on the router for 5 seconds then press the WPS button on the printer.
4. If it fails you will want to manually setup the network. The Printer's manual should be able to tell you how to do this.
Best Regards
