Julie, I just checked the PDF patterns and printed the page that has unit 8 and nothing is cut off, all the patterns are the correct size. Be sure you have the print settings for "Actual Size" or "100%". On the Paper Piecing Guide, page 23, there is a 1" test square--be sure yours printed out exactly 1". The feathers in this Feathered Star are NOT 1", they are slightly smaller than that so your patterns must be printed out the correct size for this to all fit together perfectly.
Another thought--in the beginning some people who had printing problems solved them by using a different browser, Google Chrome seemed to work well for those who had trouble with Edge or Firefox. Just another possibility for you to try.
I hope this helps.
