Please see notes before using this module

Installation

npm install hp-webscan

Scan a document

const Webscan = require("hp-webscan");
const fs = require("fs");

var ws = new Webscan("printer's hostname/ip", 1);

// See type, fmt, size definitions below
ws.scan({ type: 4, fmt: 1, size: 2 }, (data, error) => {
  if(error) {
    console.log("an error occured: " + error.code)
  }
  else {
    // Do whatever you want with the binary data
    // Here we write the document on disk using fs
    fs.writeFile(__dirname + "/scan.jpg", data, "binary", (err) => {
      if(err) {
        return console.log(err);
      }
      else console.log("Document successfully scanned and saved!")
    });
  }
})

Get a preview (much faster than a scan)

ws.preview({ type: 2 }, (data, error) => {
  if(error) {
    console.log("an error occured: " + error.code)
  }
  else {
    // Do whatever you want with data
    // Here we write the document on disk
    fs.writeFile(__dirname + "/preview.jpg", data, "binary", (err) => {
      if(err) {
        return console.log(err);
      }
    });
  }
})

• You could combine this module with node-tesseract to make a powerful ocr-scanner
• This module may not work on another version than mine, I have this one:
