The boundary between Epson device firmware, host printer packages, version identity, and lifecycle transitions.
Firmware and driver are different
Firmware is persistent code on or close to the device; a printer driver is host software that represents the device to a print interface. They can interact across a protocol but have separate identities, release records, and lifecycle owners.
Version and provenance
A firmware record should identify the exact product, device revision when documented, version, publisher, and release context. A host package record uses comparable identity fields but describes different artifacts. One version number must not stand in for both.
Capability transitions
A firmware change can alter device behavior or declared capabilities, while a host package change can alter rendering or queue metadata. Compatibility is the relationship between the resulting device declarations and host representation.
Documentation boundaries
Epson product documentation defines device-specific firmware terminology, while Microsoft Learn describes host print components. This page does not provide firmware links, update procedures, dates, or performance promises.

Questions and answers
Is firmware the same as an Epson printer driver?
No. Firmware is device-side code; a driver is host-side interface software.
Does a firmware version identify a compatible host package?
No. Device and host artifacts have separate version and compatibility records.
