DHCP is a protocol that enables a device, such as a printer, to obtain an IP address from the modem/router in the most basic explanation. When the modem/router restarts, printers will automatically collect a new IP address. However, GoMenuPOS only knows the previous printer IP address that you set, so it won’t recognize the new IP address.
This will come to the topic of why we need to disable DHCP on printers and use fixed protocol to make a static IP address.
Check the printer is connected to the network
On the back of the printer, you should see a LAN port, a solid green light and a yellow blinking light indicating that your printer is connected to the network.
Status print on the receipt printer
There is a tiny hole at the back of the printer, using some thin pointy object such as pen or pencil to press and hold for 1 second, a short docket with the current IP address will be produced. If there is nothing showing on the IP address, it means you are not connecting to the internet. For the new version of the EPSON receipt printer, it will do the status print after restart.
Some printers have a slightly different process:
1. Ensure the printer’s power is OFF.
2. Press and hold the FEED button.
3. Power printer ON, only releasing the FEED button when printing begins.
4. When you finish printing the self-test page, press FEED again and print out a paper indicating that you exit the self-test status, and back to normal mode.
5. Note down the IP address shown on docket.
Set up static IP address
