Once Primo PDF or Acrobat is
installed, open a document in Microsoft Word, select 'Print' and then under
'Printer Name' select 'Primo PDF' or 'Acrobat.' Now hit the 'OK' button
and follow the instructions.
Take note that Primo PDF is not a full-featured PDF document editor. It will simply allow the printing of documents, forms, etc. to PDF format. However, a full version of Adobe Acrobat will let you create PDF's from scratch.
