A phone is literally a computer. It takes commands and puts out signals. Whatever signals the raspberry pi puts out to the printer, the phone can do through USB.
The machine that's doing it doesn't matter. Phone, desktop, laptop, calculator, pi, Xbox. As long as the right software is there, and the machine is fast enough to do what needs to be done, any device can send out the right signals.
So USB is how you connect it to a printer.

Okay I understand now, I think it boils down to:
"As long as the right software is there"
and your lack of understanding how computers and networks work in general I guess?
Is there a "software" for your phone to control a/my 3D printer? I guess not. Java compiler is a software in itself, as are C/C++ compilers, 3D printer firmware etc. You can technically write it, but that is usually done by either a multi billion company or an open source group of hundreds, thousands of people (I mean you need to use stuff done by others to get your thing running).
Also, how do you hook your phone up to the 3D printer? It won't happen by itself.
You are right in theory, but not in practice I'd say!
Cheers

Imagine telling a software engineer that he "doesn't know how computers work". That's adorable.

Most don't so ...
Or think like just because they have a general idea if how things work, they know the nitty gritty details. Actually we all do that from time to time, but I have coded j2me on mobile phones for a couple of years, I have also used and modified C code for my 3D printer (I'm a senior C/C++ dev) so I think I'm not completely off the track. But I mean I still wait for you to show me how you'd hook a smartphone up to control a 3Dprinter. I mean it surely is possible, maybe easy, maybe very costly, but the burden of proof lies on you, not me, IMO.

Literally just get a USB cable that is designed to interface with the printer. Whatever the printer uses to interface with a raspberry pi - just plug it into your phone and there you go. I don't know what you use to connect your raspberry to your printer. Is it USB? Then connect that to your phone the same way. Is it that one weird set of pins (GPIO I think?) - then get a GPIO to USB connector.
The burden of proof isn't on me; this isn't an official Lincoln Douglass debate or cross examine debate. It's just a conversation. I hacked my PS3 with a TI89 a while back. Because the TI89 provided some code that emulated a factory reset dongle's output.
The PS3 didn't care what was providing the code. It just wanted to receive the code. I could have done that with a PC. A phone. A raspberry pi. A custom made dongle. Maybe even an analog to digital signal piano if the PS3 didn't time out on my inputs.

Okay, please show me the java code controlling the 3D printer now :-) You see, it's possible but not easily feasable.
