【Test Result】

【Solution 】

1. The currently shipped HP W1340 series remains unaffected by this firmware upgrade.

2. Some older chips in our W1340, W1350, W1410, and W1420 series may be impacted by the upgrade 

(chip produced before 24th-April 2023). For more details, please contact our sales manager.

3. However, we kindly recommend that you limit sales to managed end-users and discontinue sales to unmanaged users.

4. Please advise end-users not to manually upgrade firmware from the official website and disable the HP Automatic Update to minimize the upgrade risk.

5. If customers have found the involved products cannot be recognized by their applicable printers.

Please contact our sales manager immediately.
