An HP-registered port that turns up on HP printers and JetDirect print servers.
IANA assigns 1782 (TCP and UDP) to "hp-hcip", registered by Allen Baker of Hewlett-Packard. HP has never published a specification for it, so the honest description is the one the registry gives: an HP device protocol. In practice it appears alongside the rest of an HP printer's service set — 9100 raw print, 631 IPP, 161 SNMP — on JetDirect-based printers and print servers, and it is one of the fingerprints that identifies a device as HP.
Expose with care
Printer management and device protocols are consistently unauthenticated and are a favourite pivot on internal networks; keep printers off the internet entirely and segment them from user and server VLANs.
