The comms protocol itself is sending to 25-pin serial at 9600bps, so it’s pretty simple to rig up another way. The stuff sent is just monochrome vector art. I was thinking of either finding or making an open source (maybe Python) lib to talk to the protocol and then yeah, probably running it on a Pi as a service I could send right to from my computer. The plotter is about waist-high, so it’s pretty large. I figured I could velcro a Pi to the underside pretty easily and serve via wifi.
