Printing in mirror image

When I printed the test tower above, the numbers came out mirror imaged. IS this due to a problem building the printer?
At one point, I was told to connect the XY, XY, and Z stepper motor wires to the X,Y, and Z sockets on the motherboard.
I took a guess at which XY was X and which was Y. If this was wrong, would that cause the mirror imaging?

Thanks!

Swap the X and Y motor connections, also swap the X and Y endstop switch connections assuming the printer homes correctly at present. If you are using software endstop position corrections then you will need to swap those X and Y values too.
