を参考にavrdudeのパスを追加した後、以下を実行しました。

cd /Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin
avrdude -C ../etc/avrdude.conf -F -v -p m1284p -c arduino -P /dev/cu.usbserial-14140 -b 115200 -D -U flash:r:old-printer.bin:r

しかし、

avrdude done.  Thank you.

と出て、保存先として指定したはずのファイルもなく、おそらく吸い取りは失敗しているよう。

CH341のドライバーを入れるも失敗
