Printer: Is it possible to show print PDF and ePub url link for each node on Views?
Yes, add a global text field and under Rewrite Results select output this field as link and give the path eg. for PDF it should be printpdf/[nid].

similarly you can create one more  field for EPUB using printepub/[nid].

Note [nid] is a replacement pattern, you should add nid before these fields and exclude it from display.
