a) Please do not post in all capitals. It is difficult to read, and is
considered shouting, which is rude.
b) There are no upside-down pages in your booklet. If you re-load the paper
the wrong way around to print the reverse side, then the page will be
printed the wrong way up. If your printer tells you how to do this, either
you are not following instructions properly or your printer is wrong. If
your printer does this automatically, you will need to change the settings
on your duplexer to not rotate the reverse side.
