The PTC Advanced Print Publisher is invoked internally by the publishing framework. There are no ACL commands to run it directly. It uses a .3f template specification to translate an open XML or SGML document directly to Postscript or PDF. To support previewing, Arbortext Editor may display the PDF output using a PDF viewer such as Adobe Reader. When Arbortext Editor is using the Servidor de Arbortext PE for publishing, PTC Advanced Print Publisher always runs on the Servidor de Arbortext PE.
