Printing a Mirror Image
If you are using clear imaging media, sometimes called backlit. You may want to
print a mirror image of your plot. So that when the media is lit from behind it is in
the correct orientation. This can be done from the front panel, without changing the
image in your software.
NOTE Do not change the setting during a print, because the change becomes effective
immediately. If you change the setting in the middle of the current print, the
remaining data is printed in the mirrored orientation.
