If you are looking to control a standard office or home printer programmatically, you typically use standard web protocols rather than a proprietary HP REST API: Getting started with the REST API - | hp's Developer Portal
Uses HMAC authentication headers (Key/Secret).
import requests import urllib3 # Suppress SSL warnings for local self-signed printer certificates urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning) PRINTER_IP = "192.168.1.150" ENDPOINT = f"https://PRINTER_IP/hp/device/DeviceStatus/Status" headers = "Accept": "application/json", "Authorization": "Basic dXNlcjpwYXNzd29yZA==" # Base64 encoded credentials if required try: response = requests.get(ENDPOINT, headers=headers, verify=False) if response.status_code == 200: status_data = response.json() print("Device State:", status_data.get("deviceState")) print("Toner Level:", status_data.get("consumables", {}).get("blackTonerPercentage"), "%") else: print(f"Failed to connect. Status Code: response.status_code") except requests.exceptions.RequestException as e: print(f"Connection Error: e") Use code with caution.

Unlike traditional drivers or SNMP, the REST API uses standard HTTP methods (GET, POST, PUT, DELETE) and returns data in JSON or XML format, making it language-agnostic and easy to integrate into web apps, mobile solutions, or backend automation.
Depending on the firmware generation and enterprise configuration, the API utilizes three primary authentication methods:
