HP Event Handler
HP Event Handler is a system utility from HP that manages hardware events and communication between HP printers, scanners, and other peripherals connected to a Mac and the HP printer driver software. It runs in the background, detecting when devices are connected or disconnected and coordinating with the main HP print and scan software to enable features like automatic driver installation, status monitoring, and device configuration. It is typically installed as part of the HP print driver suite when users set up an HP printer or multifunction device on their Mac.
AI Recommendation
1 suggestionHP Event Handler is a helper component bundled with HP's printer driver software, not a standalone application. You cannot update it separately—it is updated only when you update the parent HP print driver suite itself. To check whether your HP printer drivers (and the Event Handler component within them) have a native Apple Silicon build, visit HP's support website, search for your specific printer model, and download the latest print driver. If HP has released a native driver for your printer, installing it will automatically provide the native version of Event Handler. If you are unsure which printer model you have, check System Settings → Printers & Scanners, or look at the physical device. If HP has not yet released a native driver for your particular printer model, contact HP support to ask whether an Apple Silicon version is planned—the September 2028 deadline for macOS 28 is approaching, and any Intel-only driver will stop working on that release. In the meantime, the Intel-only Event Handler will continue to work under Rosetta 2.
