Should we warn against confusing Adobe Acrobat (Pro, Standard), with Adobe
Reader?


> -MS Word 2007

Microsoft Word 2007 with the add-in "Microsoft Save as PDF" or the add-in
"Microsoft Save as PDF or XPS". As far as I know, you need to install the
extension separately.
See:
 *

 * <http://office.microsoft.com/en-us/help/save-as-pdf-HA010064992.aspx>

With Microsoft Office 2010 you no longer need the add-in, because PDF
support is included in the Office functionality:

<http://office.microsoft.com/en-us/word-help/save-as-pdf-or-xps-HA010354239.aspx>

With older versions of Microsoft Office, you need to install Adobe
Acrobat, which installs the Adobe PDFMaker (sic!) extension for Office (you
get an "Adobe PDF" menu and an "Adobe PDFMaker" toolbar.

> -Open Office 

OpenOffice.org's future is no longer certain since Oracle decided to stop
investing in it:
<http://www.theregister.co.uk/2011/04/15/oracle_letting_openoffice_go/>.
However, LibreOffice <http://www.libreoffice.org/> can also export tagged
PDF. (Just as in OpenOffice.org, you need to check the "Tagged PDF"
checkbox; it then remembers this setting for future exports. Note that in
both OpenOffice.org and LibreOffice, the PDF options contain a PDF/A
option; checking this option also checks the "Tagged PDF" option.)


> -Corel Word Perfect claims to export to tagged PDF (But I didn't test
it)

I found this claim at
<http://www.corel.com/servlet/Satellite/us/en/Content/1210622724783>.

iText is an open-source PDF library (not an end-user product!!) in Java
that appears to have some support for tagged PDF (if you know the PDF spec
well enough): <http://sourceforge.net/news/?group_id=15255>,
<http://www.mail-archive.com/itext-questions@lists.sourceforge.net/msg44991.html>,

Best regards,

Christophe
