Ethernet Printer won't connect to register

If you’re all set up on the Register app, but can’t get the receipt printer to connect, there are a couple of issues that might prevent it from connecting.

For starters, you should make sure that your register and printer are on the same network. Your printer should be plugged directly into the router for your network, and the register should be connected to that network via Wi-Fi.

If both devices are on the same network, it’s possible that the devices are on different subnets. In order to see if this is the case, we’ll have the receipt printer print out its network configuration, and then we’ll compare that to the configuration on the iPad.

First, we’ll get the network configuration from the receipt printer:

Start by turning off your printer.
Holding the Feed button down on the front of the printer, then switch the printer back on
Hold the button for 5-10 seconds, until a receipt with the printer’s network configuration prints out

Next, we need to find the network configuration of the iPad:

Find the gear icon and open your Settings.
Select Wi-Fi, and click on the network.

Comparing configurations

The numbers we’re interested in are the IP Address and Subnet Mask

On both devices, the subnet mask will most likely read 255.255.255.0 - this means that the first three sets of digits on the IP address need to be the same on each device in order for them to communicate with each other.

Images: matching IP’s = Check non-matching IP’s = X

If you check your printer’s configuration and see that your devices are unable to communicate with each due to different subnets, you’ll need to make some changes to your network setup. Typically, it’s because the ethernet network is separate from the wireless network. We recommend contacting your store’s IT professional to make these changes - feel free to have him/her contact us directly as well.
