Technical Details

what runs on :3289

ENPC is a proprietary Epson protocol assigned on both TCP and UDP port 3289. It is used for communication with networked Epson printing devices, including discovery and device-status or control operations; the exact messages and framing vary by device and are not a general-purpose printing standard. Epson devices may expose other ports for printing and administration, so finding 3289 does not by itself identify the print-data path.

3/ 10caution

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

tcp · udp

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

This port should generally be restricted to trusted local networks rather than exposed to the internet. An exposed ENPC service can disclose printer information and may permit device-control or configuration operations depending on the model and firmware; there is no reason to make this proprietary management interface publicly reachable.
