OSX printing to .pdf right justification problems

I have a 300 page document in MS Word, which I have printed to a pdf file using my Mac OSX "print to .pdf" functionality.
 
Most text throughout the Word document is set to 'right justified', and in Word all right justified lines appear as they should, both on screen and when pages are printed.
 
However, when I print that Word file to .pdf, and then view or print the resulting .pdf file, there appear perhaps 50-75 lines in the main body of the document, one every few pages, which fail to right justify.
 
There are about 200 endnotes in the document, and every single one that has more than one line fails to right justify *only on the first line of the endnote*. A clue?
 
Any ideas why this glitch occurs, or what kinds of solutions or work-arounds might address this problem.
 
This problem does not change when font is set from Times New Roman to Courier.
 
Second, the document is entirely in Times New Roman, with occasional short passages of text in italics. Lines including italicized words appear as they should in Word, but after printing to .pdf, long blank gaps appear to the left of occasional italicized words. This seems to be fixed in a fixed-width font like courier, but, is it possible to eliminate this flaw using a proportional width font?
 
No amount of fussing, resetting and re-resetting parameters, etc., resolves either problem.
 
Any ideas or places you can point me would be greatly appreciated!
