Star Micronics have an application called "TSP100III Utility" available from the Play Store. You can use this app to search for the network printer and connect to it, provided the printer is connected on your network. It can also be used to change the network settings of the connected printer to give it a static IP Address. Once a static IP address is assigned, IP address changes through the DHCP server will not occur. This means that once setup you will be able to continuously use the same IP Address for your printer.

Having downloaded the TSP100 III Utility go to your tablet's Home Screen and open the Application.

It will open and after a moment present the following screen.

At the top of the screen 'Unselected State' will flash red. Tap on it and it will search for Network printers. When it finds your printer the screen will refresh and look like the following screen.

Tap the 'Apply' button and the screen will change to the next image.

At this point your Printer is connected to your iPad and you can configure it on AirPOS or you can assign a static IP Address to the printer with a couple of clicks. To do this tap on 'Device Management' as indicated above. The screen will refresh and you'll see the following screen.

Tap on ' Login' from the left margin and in the popup enter the Username 'root' and the password 'public', as shown below and tap on 'Login.

The screen will refresh and from the left margin click on 'IP Parameters' as shown below.

In the new screen tap on Static and then enter the IP Address you got from the self print when you first connected the printer to your network (since this IP Address was assigned to the printer by DHCP there will be no conflict).

Scroll down and press the 'Submit' button. 'Save' in the left margin will flash red. Tap on it to save your selections.

Finally tap on the 'Execute' button. This will reboot the printer.

After a moment the printer will self print with '(Static)' beside the IP Address as seen below.

Notes:

You can also obtain the IP Address for your printer by holding down the feed button while you switch the printer on. It will self print a list of settings and then the red light will flash a few times while the printer acquires an IP. It will then self print it’s own settings and at the bottom of that print is the IP Address as seen above. You can input this manually after you've pressed the 'Add Printer' button by selecting 'Network' as the connection type.
