Make the printer accessible externally
Ensure that the printer is reachable via a static public IP address
Port 80 must be open for external HTTP access
Restrict access to Guestnet IP addresses
🔗 View Guestnet IP addresses
💡 Alternatively, a different port may be used for external access. Internally, a port forwarding rule to port 80 must be configured.
Enter the URL in Guestnet
In Guestnet, the following URL must be entered either in the Roomservice settings or in the respective serving location:
https://[YOUR_IP]:[PORT]/cgi-bin/epos/service.cgi?devid=local_printer&timeout=60000

How can the feature be tested
How can the feature be tested
To properly test the function, you must allow your own IP address in the firewall in addition to the Guestnet IP addresses.
Then, a print command can be sent via curl using the CLI:
curl -X POST -d "<?xml version='1.0' encoding='utf-8'?><s:Envelope xmlns:s='http://schemas.xmlsoap.org/soap/envelope/'><s:Body><epos-print xmlns='http://www.epson-pos.com/schemas/2011/03/epos-print'><text align='center'/><text linespc='0'/><text>********* </text><text width='2' height='2'/><text linespc='55'/><text>GUESTNET </text><text width='1' height='1'/><text>********* </text><text linespc='28'/><text align='left'/><text>Test </text><text> </text><cut type='feed'/></epos-print></s:Body></s:Envelope>" http://[IHRE_IP]:[PORT]/cgi-bin/epos/service.cgi?devid=local_printer&timeout=60000
Replace [YOUR_IP] and [PORT] with the correct values.
If the request is successful, the printer will print a test page, and curl will return a success message in XML format.
If an error message appears, it should be analyzed — it usually indicates a configuration issue.
If a timeout message appears after approximately 60 seconds, the printer is not reachable from the outside. This typically means the IP address was not properly allowed in the firewall, or the port is misconfigured.
