Instead of relying on OS print dialogs, your backend can POST a PDF directly to the printer using the REST API — ideal for kiosks, reporting servers, or IoT devices.
Instead of using SNMP (Simple Network Management Protocol), which has complex MIB (Management Information Base) trees, the REST API simplifies retrieving a fleet’s status. A dashboard can display 200 printers, color-coding each as “Green” (Ready), “Yellow” (Low toner), or “Red” (Paper jam) using simple HTTP GET requests.
A Python script can poll Consumables every hour. When black toner falls below 10%, the API can trigger an email to procurement or even automatically reorder from a supplier via another API. This prevents downtime without requiring users to check any control panel.
Build an internal dashboard endpoint.
const express = require('express'); const axios = require('axios');const app = express(); const printerIP = '192.168.1.100'; const auth = username: 'admin', password: process.env.HP_PASS ;
app.get('/api/printer/status', async (req, res) => try const deviceRes = await axios.get(
https://$printerIP/dev/rest/device, auth, httpsAgent: new https.Agent( rejectUnauthorized: false ) ); const statusRes = await axios.get(https://$printerIP/dev/rest/status, auth, httpsAgent: new https.Agent( rejectUnauthorized: false ) );res.json( model: deviceRes.data.model, firmware: deviceRes.data.firmwareVersion, status: statusRes.data.state, uptimeMinutes: deviceRes.data.uptime ); catch (error) res.status(500).json( error: 'Printer unreachable', details: error.message ););
app.listen(3000, () => console.log('Printer API proxy running on port 3000'));
Historically, printer management and job submission relied on heavyweight protocols such as IPP (Internet Printing Protocol) and SNMP (Simple Network Management Protocol). While effective for local network administration, these protocols present challenges in modern, cloud-native architectures. They often require complex firewall configurations and lack the granular control required by contemporary Software-as-a-Service (SaaS) applications. hp printer rest api
HP Inc. has addressed this shift by exposing printer functionality via RESTful (Representational State Transfer) APIs. These APIs allow developers to interact with HP Multi-Function Printers (MFPs) and printers using standard HTTP methods (GET, POST, PUT, DELETE), facilitating seamless integration into workflows such as secure release, mobile printing, and remote fleet management.
This is done via the printer's Embedded Web Server (EWS):
