hpdot4d
hpdot4d is a system daemon component that's part of HP's printer driver software suite for Mac. This background service handles the DOT4 (IEEE 1284.4) communication protocol, which enables bidirectional communication between your Mac and HP printers connected via USB or parallel interfaces. The daemon manages tasks like printer status monitoring, ink level reporting, and advanced printer configuration options. It's automatically installed alongside HP printer drivers and runs silently in the background to ensure proper printer functionality and communication.

1 suggestionBased on the available information, hpdot4d is part of HP's legacy printer driver package. Apple now provides more recent HP printer drivers through official channels, as evidenced by the Apple-distributed HP Printer Drivers (version 5.1.1) available through Homebrew. For better Apple Silicon compatibility, you should download the latest HP printer drivers directly from Apple's support website or use the drivers that come built into macOS, which are typically Universal binaries. You can also check HP's official support website for the most current drivers for your specific printer model.
