True, although Octoprint is typically for making local devices network connectable to receive and manage prints. A traditional PC is better if it's expected to do any processing of models, but a $5 rpi0w powered by the bus is generally plenty. Our challenge was scalability and portability. Printers in our farms often moved between labs and offices, and toting a whole PC with each one would have been limiting to where they could be set up, as well as create potential conflicts with IT policy. It was also simpler to image SD cards than hard drives (or to work with IT to create and manage deployable configurations). In the end, $35/printer for raspi3b+s wasn't a big overall expense, unlike the time spent on training and maintenance. Now we pay 10x more for faster, higher quality printers that don't break down AND include network ports, but we only need 1/5th as many to operate at the same capacity.
