    Internet Printing Protocol (IPP) for nodejs

    A pure Javascript implementation of the IPP/2.0 protocol that has no dependencies.

    The IPP protocol was started in the 90's and is still being worked on today. It is a very indepth protocol that spans many RFCs- some of which are dead while others were herded into IPP/v2.x.

    There are millions of printers that support IPP. If you have one, this module will allow you to send/recieve data to/from the printer.

    To find out if your printer supports IPP:

    • Google your printer's specs
    • Try: telnet YOUR_PRINTER 631. If it connects, that's a good sign.
    • Use the '/examples/findPrinters.js' script.

    I have a pretty good starting point here. I created reference files (attributes, enums, keywords, operations, status-codes, versions and tags) and tried to include as many links in the comments to the ref docs as I could.


    $ npm install ipp

    Printer(url [,options])

    var ipp = require('ipp');
    var PDFDocument = require('pdfkit');
    //make a PDF document
    var doc = new PDFDocument({margin:0});
    doc.text(".", 0, 780);
        var printer = ipp.Printer("http://NPI977E4E.local.:631/ipp/printer");
        var msg = {
            "operation-attributes-tag": {
                "requesting-user-name": "William",
                "job-name": "My Test Job",
                "document-format": "application/pdf"
            data: pdf
        printer.execute("Print-Job", msg, function(err, res){

    To interact with a printer, create a Printer object.

    Technically speaking: a Printer object does not need to be an actual printer. According to the IPP spec, it could be any endpoint that accepts IPP messages. For example; the IPP object could be persistant media- like a CD ROM, hard drive, thumb drive, ...etc.


    • charset - Specifies the value for the 'attributes-charset' attribute of requests. Defaults to utf-8.
    • language - Specifies the value for the 'attributes-natural-language' attribute of requests. Defaults to en-us.
    • uri - Specifies the value for the 'printer-uri' attribute of requests. Defaults to ipp://
    • version - Specifies the value for the 'version' attribute of requests. Defaults to 2.0.

    printer.execute(operation, message, callback)

    Executes an IPP operation on the Printer object.

    • 'operation' - There are many operations defined by IPP. See: /lib/enums.js.
    • 'message - A javascript object to be serealized into an IPP binary message.
    • 'callback(err, response)' - A function to callback with the Printer's response.


    Parses a binary IPP message into a javascript object tree.

    var ipp = require('ipp');
    var data = new Buffer(
        '0200' + //version 2.0
            '000B' + //Get-Printer-Attributes
            '00000001'+ //reqid
            '01' + //operation-attributes-tag
            //blah blah the required bloat of this protocol
            '470012617474726962757465732d6368617273657400057574662d3848001b617474726962757465732d6e61747572616c2d6c616e67756167650002656e' +
            '03' //end-of-attributes-tag
    var result = ipp.parse(data);
    //  ta-da!
    // "version": "2.0",
    // "operation": 11,
    // "id": 1,
    // "operation-attributes-tag": {
    // "attributes-charset": "utf-8",
    // "attributes-natural-language": "en"
    // }


    Converts an IPP message object to IPP binary.

    See request for example.

    ipp.request(url, data, callback)

    Makes an IPP request to a url.

    var ipp = require('ipp');
    var uri = "your_printer";
    var data = ipp.serialize({
        "operation-attributes-tag": {
            "attributes-charset": "utf-8",
            "attributes-natural-language": "en",
            "printer-uri": uri
    ipp.request(uri, data, function(err, res){
            return console.log(err);
    //  ta-da!.. hopefully you'll see a ton of stuff from your printer
