Thank you for the update, I’ll try the file and will update here.
I have tried the patch 27678626 for the UB-03. Unfortunately in the UB-03 Ethernet card
SNMP Support – Not Available
SNMP Setting – Removed
Firmware version labeled 1.03+M2.00.
Above patch didn’t work. But I’ll be trying with Local TM-U220 printer (Non Oracle Micros Printer).
