After some research, it was determined that it would be relatively simple to have an Arduino convert incoming serial data into a parallel output to the printer.

An Arduino Uno provides the processing power and drives the serial monitor. A joystick and a Hitachi H48C accelerometer are mounted on a breadboard and wired to the Uno.
