New firmware file format
This bulletin was created to inform you of the new file format for the EpsonNet Print Server
firmware and WebAssist updates. The new file format combines both the firmware update
and WebAssist update into a single file with a .efu extension. WinAssist v4.1aE is required to
update the EpsonNet Print Servers with the update files in the new format.
EpsonNet WinAssist 4.1a or later supports these new firmware update files.
