You don't mention the brand of printer but Epsons (and other brands) have had this problem in Appleworks because of the setting of fractional character widths. The symptom is that the characters on the right margin may be clipped and words may be only partially printed, if at all.
Open Appleworks. Go to the Edit menu, under preferences, click on text and toggle the check for "use fractional widths" to the opposite setting (if it is checked then uncheck it, if it is not checked then checkmark it). Close everything and quit AW, open AW and the document and try to print it.
This was a common problem between both AW and Word and some printer software. Most companies updated the software and eliminated the problem. Check the website for your printer to see if there is an update.
