The catalog listing for this specific unit does not include a specific HP part number, so the exact compatible printer models and page-yield rating cannot be confirmed here - HP's Managed line spans many different toner part numbers across its various LaserJet printer families, each matched to a specific printer model or series. "Managed" cartridges are typically supplied as part of a contracted print-fleet agreement where a business pays per page printed rather than buying consumables outright, with HP or its channel partner tracking and replenishing toner automatically as needed.
