Mi código es el siguiente:

----Vista---
<h:commandLink>
<h:graphicImage value="../images/downloadPdf.png" height="70" width="85" />
<p:dataExporter type="pdf" target="idDataTable" fileName="Archivo PDF" pageOnly="false"
preProcessor="#{bean.preProcessPDF}"/>
</h:commandLink>

----- BEAN ---------

public void preProcessPDF(Object document) throws DocumentException, BadElementException, MalformedURLException, IOException {
Document pdf = (Document) document;
pdf.setPageSize(PageSize.LEGAL.rotate());
pdf.setMargins(-0.10f, 0.0f, 30.5f, 1.5f);


if (!pdf.isOpen()) {
pdf.open();
ServletContext servletContext = (ServletContext) FacesContext.getCurrentInstance().getExternalContext().getContext();
String logo = servletContext.getRealPath("") + File.separator + "comun" + File.separator + "images" + File.separator + "topImage.png";
System.out.println("logo: " + logo);
pdf.add(Image.getInstance(logo));
}
}

By looking at the iText api and see how to create headers/footers

[sudheer]

This requirement is not related to Primefaces but related to iText library only.You can try to add logo in the header section or follow any solutions from iText library side.
