To set up your TSP143 wifi receipt printer there are two options.
Connect by WPS Pairing Button
1) If your router has a WPS pairing button you can hold down the WPS button on both the Star printer and router at the same time. This will connect your printer directly to your wireless network on your router.
Connect by AP network mode
2) If your router does not have a WPS pairing button the second option is to manually connect the printer to your wireless network via a manual IP Address.
Connecting your printer to your computer by the AP network mode involves:
Printing your Network Configuration and Current IP Parameters.
Setting your wireless LAN settings.

Once your Network Configuration and Current IP Parameters Status print successfully, release the FEED button.
