TCP Socket Port: Transfers printing data and printer status by direct socket communications (bi-
directional).
Automatic IP Address Assignment Protocols
The UB-E04 supports DHCP and APIPA, the protocols that assign an IP Address automatically. Automatic IP
address assignment is performed with the protocols in the order of descending priorities shown in the
table below. If automatic assignment with one protocol results in "disabled" or "failure," the subsequent
protocol is used.
Protocol for acquiring status and setting
The following protocols are used to acquire the status and set for the UB‐E04.
•
SNMP:
The general purpose MIB management tool, OPOS/APD, uses this to acquire and set
the TM printer status.
