very nice looking printer.
As far as networking printers go, unless you can upload the gile in one go and then print it exclusively from the machine - why would you bother ?

How far a walk do the mechanical guys have ?
Given how long a 3d print can take - is it really an issue ?

We do have a few members who network via octopi.
Can't find any connection info on the creatbot website.

Is it possible to print directly from the slicer via a usb cable ?
In which case you could build a mini-itx system, connect that to your network and run it via teamvieer or similiar remote software.
I got a mini itx board, i3 chip and 4gm ram last week for ?35 quid. You can get a 120gb ssd for about ?15, windows 7 ultimate off ebay with genuine serial for about ?3, cheap case for ?30 and job's a good un.

If the slicer will run linux or android - use a raspberry pi - which you apparently already have.

By the sound of it you're trying to connect directly to an interface on the printers motherboard. And if the firmware doesn't support that - no it's just not going to work.

Ah - apparently it does have usb connectivity.
So that's the way I'd probably do it. network an attached computer and print directly over usb from that.

Or just let the mechanical guys get the odd bit of exercise :-)
