I got @Simplify3D up and running and it works well with gcodeprintr .
Simplify3D has an option to configure a post-processing script (like Slic3r did). This allows you to add GCodeSimulator as a post processor to use the wireless send function to send the gcode to gcodeprintr .

All you need is a bash script (under Linux) similar to this one and enter the full path to it into Simplify3d (see screenshot):
#!/bin/bash
java -jar /3dprint/GCodeSimulator.jar “$1” &

A Windows start script should be straight forward as well.
It starts the post processing script once you choose “save toolspath to disk”
