Geeetech

i have just started test printing on my new Geeetech mini G2 and the print out is mirrored, but the print preview in the repetier-host is not.
Please help.

I have this same issue that the text characters that I print end up mirrored/reversed.
In repetier, setting the "invert x, y or X*Y" doesn't fix the issue. It just changes which way the head moves when I press the manual movement control.

Is this a setting that needs to be changed in the firmware/configuration.h?
