Everybody's printer is different, but in mine, I can choose page ranges in
two places--the Print dialog defaults to Copies and Pages, or if I change
the dropdown menu to MS Word, I can pick odd/even pages. Which are you
referring to?
Regardless, it probably makes sense to see if reinstalling the printer
driver helps--drivers can corrupt and it is not inconceivable that it would
only affect Word.
Also, there appear to be two different problems here--you are saying the
options are entirely absent--others said they were unable to enter anything
in the page ranges boxes, but could see them.
