I use Cura for creating the G-code files for my (2 1/2 year old) Prusa i3.

I have to put the prints in the corner furthest from the X-Y-Z origin symbol as the machine prints in the middle of the bed. How do I remove this offset?

Not being able to see your settings, or your G-code, it is difficult to say. If it is slicer settings related, a common mistake is that the "origin at center" option is active. You should remove the tick mark at "origin at center" in the printer settings of the printer profile you use in Ultimaker Cura. Your origin is not in the center, it is left-front.

Another possibility is that the offset of your printer origin is way off. To check that you should connect the printer over USB and use programs as Repetier host, Pronterface, etc. to instruct the printer to go to (0,0,0) and see where the head ends up. You can also do this by printing a G-code file with homing code (G28) and a movement instruction (G1 X0 Y0 Z1 F1500). If the head moves to the left front, you know the printer is correctly setup, and you should look at the slicer.

E.g. when M503 is send in a terminal to the printer over USB, amongst the output you can find:

... Recv: echo:Home offset (mm) Recv: echo: M206 X0.00 Y2.00 Z0.00 ... 

When the X and Y values are high, this can also cause the printer to have a large offset.
