With cloud rendering and the ezeep Hub, all printjobs are rendered in the cloud. This involves our Render Server (RS, Windows Server 2016) and Render Worker (RW, Windows Server 2019), VMs in our Azure cloud that run our rendering service. To be rendered properly, the specific model driver must be hosted on these machines. Since there are hundreds of thousands of printer models and thus printer drivers, many customers will contact us asking us to add a driver. The full procedure for this can be found here.
