Print Cartridge Expiration Date?

[SNC205]

Hello, I am wondering if the printed date on the exterior box of the 655A catridges is an expiration date.

No, that is not an expiration date.

The date of manufacture included on some toner cartridge boxes is intended for HP internal processes and may be required to comply with regulatory standards in certain countries. The date of manufacture is not an expiration or “use before” date.
