ipp-browser
IPP-browser is a powerful library that brings the power of Internet Printing Protocol (IPP) directly into the browser. Inspired by the work of William Kapke, this library extends the use of IPP to the browser. With this library, you can easily integrate printing to IPP-compatible network devices directly from your web applications without having to rely on additional plugins or software.

npm
$ npm install @cphillips/ipp-browser --save
