hp-info is a command-line utility from the HPLIP (HP Linux Imaging and Printing) package, used to retrieve and display comprehensive information about connected HP printers, scanners, and multifunction devices on Linux systems.

Without specifying a device, it scans for all supported HP devices and shows basic details like model, serial number, status, and backend. When targeting a specific device via URI, bus ID, or model, it offers an interactive menu with categories such as:
  - Device status and capabilities
  - Aligned devices and printhead info
  - CUPS print queues
  - Firmware and plugin status
  - Supported commands and error log

This makes it essential for troubleshooting detection issues, verifying driver compatibility, checking firmware versions, and confirming plugin installations required for proprietary features. Output is formatted for readability, aiding system administrators and users in diagnosing printing/scanning problems.

Requires HPLIP installed; sudo may be needed for full USB/net access.

Requires HPLIP package; some info needs root privileges or running HPLIP services; proprietary plugins must be installed separately for full device support.

hp-info (lists all devices)
hp-info -d hp:/usb/HP_Device_1234_ABC (device-specific info)

Outputs menu like [0] Device status, [1] Aligned devices, [q] Quit; enter number to view section.

Developed as part of HPLIP project initiated by HP in 2001 for Linux/UNIX printing support. First released in HPLIP 0.9 (2005); evolved through versions to HPLIP 3.24.x (2024), adding support for new devices, plugins, and enhanced diagnostics.
