leitzicon v0.0.1

Leitz Icon label printer

A node.js module to print labels using the Leitz Icon printer.

It uses the Internet Printing Protocol (IPP), which is the prefered option when printing over wifi.

It also uses the png2lwxl node.js module, written by me, to convert PNG files to the appropriate printer format.

Install

You can install leitzicon using the Node Package Manager (npm):

npm install leitzicon

Simple example

var leitz = require('leitzicon');
var fs = require('fs');

leitz.printPNG(__dirname + '/test.png', 'http://192.168.1.1:631/ipp/print', {}, function (err) {
    if(err) return console.log(err);
    console.log("print complete");
});

png2lwxl options

• landscape: rotates image 90 degrees default = false.
• blackwhiteThreshold: enter a value between 0 and 255. The higher the value, the more pixels will be treated as black default = 128.

example with options

var leitz = require('leitzicon');
var fs = require('fs');

leitz.printPNG(__dirname + '/test.png', 'http://192.168.1.1:631/ipp/print', {
    landscape: true,
    blackwhiteThreshold: 110
}, function (err) {
    if(err) return console.log(err);
    console.log("print complete");
});
