P) DHCP Printer Troublshooting

How to enable DHCP on printers so they can communicate with your network!

Your Epson receipt and kitchen printers communicate with the Dripos POS through your Network. When you set up your printers, your printers should automatically generate an IP Address within your Network. Sometimes printers fail to connect to the POS Network because the printer DHCP is disabled and needs to be enabled in order to connect.

In this article you will learn how to enable DHCP for your printer. If you factory reset your printer or are trying to set up a printer that you did not purchase from Dripos, you will need to enable DHCP and manually configure your printer.


How Do I Know if a Printer's DHCP is Disabled?

To check if DHCP is enabled or disabled on your printer, you will need to print a test or IP slip by turning the printer off and turning it back on again.  After you print the test slip, locate the section of the slip that shows the following information:

IP Address    : 192.168.192.168

SubnetMask    : 255.255.255.0

Gateway       : 192.168.50.1

DHCP          : DISABLED

Next to DHCP, check if the status says Enabled, Disabled, Acquiring - Manual or Static.

Note: If the DHCP is Enabled, your printer should be able to automatically generate an IP address that connects the printer to your POS network and you do not need to follow the steps in this article.

If the IP Address is valid (ex: 192.168.50.2), you may need to simply add the printer to printer settings in order for it to start printing. If the IP Address is 192.168.192.168 your printer is not connected to the internet and cannot locate your POS network.

Check that the ethernet cable is firmly and correctly connected between your printer and router (or switch) and is a working cable. You should also check if you internet is working and other devices are online.

Steps to Enable DHCP

If the DHCP status says disabled, acquiring - manual or static and the IP address says 192.168.192.168, your printer cannot connect to your POS network.

You will need to enable DHCP to finish setting up your printer. To enable DHCP you will need to leave your printer connected and use an iPad for the configuration.

6. Change the IP address to match that of the printer with the exception of the last set of numbers. For example, if your printer has the IP of 192.168.192.168, set the iOS terminal IP Address to 192.168.192.xxx, replacing the xxx with any number from 2-254 that is not already the device itself (Ex: 192.168.192.115). Set the Subnet Mask to 255.255.255.0 and the Router (gateway) to the IP of the printer (Ex: 192.168.192.168).

7. Click Save
