One possibility is to use a PC to upload jobs to farm printers controlled by Duet 2 boards, via HTTP/Ethernet. The jobs are stored on the SD cards of the individual Duets and run from there. The PC also interrogates the printers via HTTP to determine when a job is complete; then it removes the printed object (using commands sent to the Duet, or a separate system) and uploads a new job.
I know we have at least one industrial customer using this or a similar method. If you go this route then it's best to use industrial grade SD cards, not consumer grade.
