Surprise! If DSR is ever low, the serial device gives that error.
|The DTR output on my plotter is run directly to the DSR pin, but I have

Connect DTR from the printer to CTS. leave the Amiga's DSR input alone.
Apple uses the bizare concept of "DTR" handshake; by connecting to
CTS you will be emulating "real" CTS/RTS handshake.
