I have been working on Print Relay[1], a cloud-based print relay system that enables remote printing to any printer connected to your local network.
PrintRelay consists of a cloud server and lightweight clients that connect printers to the cloud via WebSocket.
We use the excellent SaaS PrintNode at work, but about twice a year we have connectivity/routing issues between AWS ap-southeast-2 and their servers OS. PrintRelay is my attempt to not need PrintNode. Because of this PrintRelay is PrintNode API compatible.
