This is a quick troubleshooting section for when you are unable to print from your computer:

• Ensure the computer you're receiving the device on is on the same network as the printer (same wi-fi network).
• You are printing with a recommended Epson printer.
• The IP address of the printer has not changed. 
• The printer is on your local network and not a network generated from your POS.
• Check all cables are installed and connected correctly. 
• Ensure you have enabled 'Safe Scripts'.

If you have confirmed the above and still can't manage to get the printer working, then please contact WOWAPPS support.
