That sounds neater than what I ended up doing.  However I've yet to
figure out how to do what I want with a portal_types action.  Care to
give a hint how to clean up the below with portal_types?

Using:

  http://cmf.zope.org/Members/jshell/News/PrintablePage
  http://www.easysw.com/htmldoc/
  http://www.zope.org/Members/mjablonski/howtoPDF/

Getting it all to work took four steps:

  1) Installed htmldoc.  (There's a Debian package)

  2) Getting html2pdf.py happy with Plone.  The essential changes were
  to change the condition to:

        if self.meta_type=='Folder':
                html = self.index_html(self,self.REQUEST,self.REQUEST.R$
        else:
                html = self()

  3) Creating a new, "printable" skin:

    a) Created a "printable" folder under portal_skins.

    b) Copied main_template from portal_skins/plone_templates to the new
    printable folder.

    c) Edited main_template in the printable folder such that the guts
    looks like:

--<cut>--
<table class="columns">
    <tbody>
        <tr>
            <td class="main" 
                tal:define="global show_border python:here.showEditableBorder(template_id=template.getId(), actions=actions);">

                <metal:block metal:define-slot="super"
		             tal:condition="show_border" >

                <div class="contentBar">        
                &nbsp;
                </div>    
            
                </metal:block>
            
                <div class="document"
                     tal:attributes="class python:test(show_border, 'editableDocument', 'document')">

                    <metal:block metal:define-slot="main" tal:content="nothing">
                    Page body text 
                    </metal:block>
        
                    <metal:block metal:define-slot="sub">
                    <tal metal:use-macro="here/viewThreadsAtBottom/macros/discussionView" />
                    </metal:block> 
                </div>
            </td>
        </tr>
    </tbody>
</table>
--<cut>--

    d) In portal_skins Properties added a new skin, "printable", and
    copied the value of the Plone Skin, "Plone Default" to it.

    e) Prepended "printable" to the new printable skin value.

  4) Getting a PDF link on all pages:

    a) Copy, "navigation_slot" from
    portal_skins/plone_templates/ui_slots to the custom folder.

    b) Edit, "navigation_slot" to add the following section at the end
    of the tbody tag:

--<cut>--
        <tr class="odd">
            <td colspan="2">

               <a href="../folder_contents"
                  tal:attributes="href string:${here/absolute_url}/html2pdf?plone_skin=printable">
                   <img src="dummy.gif" 
                        alt=">" 
                        border="0" 
                        tal:attributes="src string:$portal_url/linkTransparent.gif" />
                  PDF
               </a>
            </td>
        </tr>
--<cut>--

Done.

Caveats: On very brief checking it seems to work everywhere EXCEPT for
the root of a Plone site where it gives an AttributeError on:

  Traceback (innermost last):
    File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 150, in publish_module
    File /var/lib/zope/Products/Localizer/__init__.py, line 57, in new_publish
    File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 114, in publish

      (Info: ((&lt;CMFSite instance at 8eaf7c8&gt;,), {}, None))
    File /var/lib/zope/Extensions/html2pdf.py, line 20, in html2pdf
      (Object: site)
  AttributeError: (see above)

Where line 20 is a call to self() in my edited html2pdf.py.  

I haven't attempted to debug this.  Its late, I'm tired.  Directions on
how to make this cleaner via portal_types would be most appreciated.
Heck, I'll promise to doc this all on the dogbowl for some cleanup
assistance...
