### Brief description of your issue

### Package
EPSON.EpsonNetPrint

### Description

The current winget manifest for EPSON.EpsonNetPrint (version 3.3.1) only tracks the EU release,
distributed from Epson Europe's server:
https://download.epson-europe.com/pub/download/6741/epson674187eu.exe

However, Epson Japan's official support site distributes a separate, independently versioned
release for the same product:

- Product page: https://www.epson.jp/support/portal/download/px-s5010.htm
- Version: 3.1.4
- Last updated: 2023-10-10

Because winget only tracks the EU version line, `winget upgrade` reports version 3.3.1 as an
"available upgrade" for users who intentionally installed the Japanese release (3.1.4.0),
even though 3.1.4 is the current/latest version on Epson's official Japanese distribution
channel. This is misleading, and running `winget upgrade` on a JP install may silently replace
the Japanese-language build with the EU build (potentially English-language UI).

### Additional context
The manifest (PR #385991) was submitted
by a community contributor (DandelionSprout), not by Epson directly. The contributor's own PR
comments note they had difficulty finding an official installer URL and were unsure about the
installed program's exact behavior, and reviewers likewise could not fully verify runtime
behavior without Epson hardware. This suggests the EU-only version tracking may be an
unintentional oversight rather than a deliberate decision to unify regions under the EU version.

### Steps to reproduce

1. Install EpsonNet Print (Japanese version 3.1.4.0) from Epson Japan's official site.
2. Run `winget upgrade`.
3. Observe that EPSON.EpsonNetPrint 3.1.4.0 → 3.3.1 is offered, sourced from
download.epson-europe.com.

### Actual behavior

winget presents the EU release (3.3.1) as a strict upgrade over the JP release (3.1.4.0),
despite these being separate, independently versioned regional builds.

### Expected behavior

Either:
- The manifest should be scoped/labeled to make clear it tracks the EU build only, and not be
offered as an upgrade path for JP installs, or
- A separate locale-specific manifest (e.g. EPSON.EpsonNetPrint.JA or similar convention)
should track the Japanese release independently.

### Screenshots and Logs

_No response_

Start by comparing the EPSON.EpsonNetPrint manifest at version 3.3.1 with Epson Japan's 3.1.4 release and review PR #385991. Reproduce the reported 3.1.4.0-to-3.3.1 result with winget upgrade, then determine whether the manifest should be scoped to EU or a separate Japanese manifest is needed; done means JP installs are not misleadingly offered the EU build.
