Repetier server is a print management software which can be installed on your own hardware. There are versions for Raspberry Pi, Windows, Linux and Mac. Repetier server can be used for two printers for free. To operate with more printers a "light" or "pro" version is needed (one time payment without subscription).

Please note: the method provided below is not tested yet! We prepared this rough guidance based on information provided by Repetier in their support forums and user manual (se sources below).
According to Repetier, the only step which is need to be done is sending a corresponding command to the server (perhaps using _console):
@autostartNextJob (if you are using Repetier version 1.2.0 or newer)
@autostart_next_job (if your Repetier version is older than 1.2.0)
Since the loading and ejecting routine for JobOx is already included in your GCODE file (JobOx slice profile is mandatory!) no additional code is needed (neither before nor after a print). After the printing job is finished and the building plate is ejecting the next print job in the queue will be started automatically.
