The ezeep.js JavaScript library implements the ezeep Blue API to easily offer printing capabilities to any web application. Integrate a printing feature to your web application with just a few steps.
-
Sign up for an ezeep Blue account. This creates an administrator account and a new ezeep organization. Sign up here. After successfully signup, you can manage your ezeep organization here.
-
Register your web application to receive your Client-ID. Contact the ezeep team at helpdesk@ezeep.com and provide the Redirect Uri of your web application. This Uri must host the ezeep.js component. (Here are more details on OAuth workflows and Client-ID/Redirect Uri)
-
Download the ezeep Blue Connector and install it on a machine (e.g. your local machine) with a printer on the same network. After the installation you are prompted to authenticate with your ezeep Account. Your printers in your network will be discovered automatically and advertised to the ezeep Administration Portal.
ezeep.js is available as Angular library as well. Instructions on how to setup ezeep.js with Angular can be found here.
Important: You need to set up your server with https!
- Include ezeep.js to your web app by the following options:

The stencil.config is already set up to do exactly this in your development environment.
You'll need a certificate and key for this aswell as a .env file placed at the root of the project.
To generate a self signed certificate execute the following command (use (git) bash!):
openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out certificate.pemand follow the steps to generate a key.pem and certificate.pem.
In your .env file specify the following variables:
DEV_SERVER_ADDRESS="your-server-address.com"
DEV_SERVER_PORT= portnumberAdditionally, you need to uncomment the "devServer" option in the stencil config file.
