How to Set a Static IP Address

How to Set a Static IP Address

An IP Address stands for Internet Protocol Address and it serves two principle functions, host or networking interface identification and location addressing.

This page explains the differences between DHCP (dynamic) and static IP addresses for Star printers, which would be more suited to you and how to shift between them (Star TSP100 Series).

What’s the Difference Between DHCP (Dynamic) and Static IP Addresses?


DHCP (which stands for Dynamic Host Configuration Protocol) is the default setting for all Star printers. In DHCP mode an IP address will be automatically provided along with other related configuration information.

The benefit of using DHCP is automatic and reliable IP address configuration, which minimises errors caused by manual IP configuration. With this method you can quickly connect a printer to your iPad, as shown here.

There is, however, a downside to the convenience of DHCP. If your internet router is switched off for any reason, perhaps you unplug it or there’s a power outage, the printer will be given a new IP address. This is important to know because when you connect your iPad to a Star printer, it connects using the IP address the printer has at that specific moment. An IP address is how your iPad communicates with the printer and if the IP addresses don’t match, information cannot be sent from the iPad to the printer and you will be unable to print anything.

This means you’d have to reconnect your iPad(s) to your printers each time your internet router loses power, is reset or is switched off. They can be quickly reconnected using the method you originally used to connect the printer to the iPad, so it’s not the end of the world. If, however, you have more than one printer, we recommend changing them to static IP addresses to avoid this issue.


Static IP addresses are manually configured and, after being set, will remain unchanged. This is why they are sometimes referred to as fixed IP addresses. Even if your internet router is disconnected or loses power, a static IP address will stay the same.

As we mentioned previously, mobile devices such as iPads connect and communicate with network printers through an IP address, which, if on DHCP, change every time the router is restarted. Setting a static IP means you won’t have to reconnect your iPad to the printer each time your router is reset. If your business suffers from frequent power outages, we recommend this option for your printers.

Steps to Setting a Static (Fixed) IP Address

1. Download the TSP100III Utility app from the App Store.

2. Ensure your Star TSP100 series printer is switched on and connected to your internet router.

Check this by turning the printer off, followed by pressing and holding the FEED button as you switch it back on (Hold down until it starts printing). Two receipts will be printed, the second showing the printer’s current network configuration, as shown below:

At the bottom of the receipt, underneath the Current IP Parameters Status, make note of the Subnet Mask and Default Gateway as you’ll need them for later.

3. Open the TSP100III Utility app and tap on the Selected Device field as highlighted below.

Do not have your iPad plugged into your computer when scanning for the printer as it can interfere with detection.

4. Your printer(s) should appear in this list. Select the one you wish to connect to, followed by tapping Apply.

5. Tap on Device Management.

6. Tap on the Dynamic (DHCP) toggle. This will switch the mode to Static.

7. The three fields below can now be edited. To keep things simple, copy the IP Address, Subnet Mask and Default Gateway from the receipt you printed out previously (As shown in step 2).

Now change only the last grouping of numbers of the IP address (i.e

For example, in the case of the receipt shown in Step 2, the IP address "" would be changed to ""

The default DHCP address range is typically between 100 and 156, so you’ll want to avoid all of the addresses between and when you’re assigning static IP addresses.

Each printer must have its own unique static IP address. If a duplicate exists, you may experience some unexpected results when trying to print.

After changing them, tap the Apply button.

8. The printer should print out a new receipt with the updated IP address. The word (Static) should be printed next to it, as shown below:

You have successfully changed the printer’s IP address!

When adding a printer to the system, you can use the Printer Network Address field to manually input the printer’s IP address (as shown here).
