Use official, model-specific firmware guidance and understand supply compatibility before updating.
Separate firmware from the print app
Firmware is software running inside the printer. A driver or mobile app runs on your device. Updating one does not necessarily update the other. Use the official support page for the exact printer to identify the available updates and the supported installation route.
Read the compatibility notes
HP notes that firmware can improve functions and address security issues. On dynamic-security models, updates can also affect cartridges that use non-HP chips or modified circuitry. Review the model’s current supply requirements and release information before changing firmware.
Choose a sensible update window
Finish urgent jobs first, follow the update instructions and keep the required power and connection available until completion. In a managed workplace, coordinate with IT. Automatic-update options and requirements can depend on the model and any connected service you use.
