The short answer
The driver is computer-side print support. Firmware is software stored in the printer that controls its own operation. Installing a driver does not update the printer's firmware.
Where this applies
This distinction applies across brands and operating systems, but firmware requirements are model-specific. Some printers rely on built-in OS print support or AirPrint rather than an additional downloadable driver.
Identify the right device and prepare
Find the exact model and read its manufacturer support page. Determine whether the proposed file is a print driver, an application, or firmware; check the stated purpose and prerequisites.
Work through the checks in order
A driver update might add a supported page-setting option on a computer. A firmware change may alter how the device itself handles jobs and typically requires a separate device-specific procedure.
- Identify where the change is applied: to the computer's print path for a driver, or to the printer's internal system for firmware.
- For a printing problem, test queue, connection and output first. Do not infer that a firmware update is necessary merely because a driver update was offered.
- If official documentation identifies a relevant firmware issue, read the exact model's update instructions, power requirements, compatibility notes and recovery advice before deciding whether to proceed.
- If the vendor's instructions are unclear or the printer is business-critical, contact official support or the administrator instead of improvising an update.
Expected result and next branch
You can identify the correct class of package and decide whether it addresses the observed symptom. No firmware installation is required to complete this explanation.
If the manufacturer offers no firmware for your exact variant, do not use a similarly named model's file. For unsupported devices, ask official support about options.
Safety and limits
Firmware interruption can leave a device unusable; the cited HP model documentation specifically warns against power-cycling during its update. Follow your own model's instructions rather than copying another model's steps.
