How to set up a Star TSP100iii receipt printer on a Mac computer (Wireless)

This article will show you how to install your Star Tsp100iii receipt printer on a Mac computer.

If you haven't purchased your receipt printer yet, we highly recommend purchasing a wired USB receipt printer instead of a wireless or Bluetooth printer, as wired printers are typically less complicated to set up.

Note: This article is specifically related to the Star TSP100iii wireless model. If you have the wired TSP100 or TSP143 model, click here.

Connecting your printer

  1. Connect the power cord to your printer and an electrical outlet.
  2. Turn on the printer and wait for the blue Ready light to become solid


Inserting your paper roll

  1. To open the printer's lid, push the latch on the right away from you and lift the lid upwards.
  2. Inset the paper roll in the orientation below.
  3. Pull the paper out past the cutter at the front of the printer.
  4. Push the lid down to snap the latch shut.


Connecting your printer to your wireless network

The simplest way to connect your printer to your wireless network is by WPS. If your router supports WPS, it will have a button with this logo wps_logo_small.png.

Note: If your router does not support WPS then you can connect by the AP network mode however this can be quite technical, and we would highly recommend getting a router that has WPS instead.

Connect by WPS

  1. On the back of your printer, press and hold the red PAIR button until the blue Ready light in front of the printer starts blinking.
  2. On your router, press the WPS button.

Note: Steps 1 and 2 need to be done within 30 seconds of each other.

  1. Once the connection between your printer and router is established, the Ready light will be solid and your Network Configuration and Current IP Parameters Status will print automatically.

Note: If a connection is not established after repeating steps 1-3, refer to Star Micronic's FAQ - Cannot connect to network article.

  1. Under Current IP Parameters Status, take note of the IP Address. This is your printer's new dynamic IP address.

Connect by AP network mode

Connecting your printer to your computer by the AP network mode involves:

  1. Printing your Network Configuration and Current IP Parameters.
  2. Setting your wireless LAN settings.

Printing your Network Configuration and Current IP Parameters

  1. To turn off your printer, press the power switch on the left.
  2. While your printer is off, press and hold the FEED button on the front of your printer.
  3. Still holding on to the FEED button, turn on your printer using the same power switch.
  4. Once your Network Configuration and Current IP Parameters Status print successfully, release the FEED button.
  5. Under Network Configuration take note of the SSID. This is your printer's 'name' on your network.
  6. Under Current IP Parameters Status take note of the IP Address. This is your printer's default static IP address.
