I have Office Web Apps Server 2013 SP1 with March 2015 CU applied. The version shows up as "15.0.4569.1506" using Todd Klindt'smethod. When anonymous users view the Word documents online through the Office Web Apps, they have an option to print them to PDF. The PDF file that gets generated as a result isn't accessible (i.e. it isn't WCAG-compliant). using Adobe Acrobat Pro to check it I can see that it is missing tags, for example. The source Word document was made fully accessible from the point of view of Microsoft Office accessibility tools.
When viewing the same document in Word Online in Office 365, I get an extra option "Download as PDF". The PDF document produced is accessible. If I save a Word 2013 document as a PDF from within the Word editor, it also generates accessible PDF.
I was wondering if the reason for the accessibility problem that I have misconfigured my on-premises Office Web Apps, or perhaps the accessibility compliance isn't built in yet. If the latter is true, I was wondering if someone could indicate whether or not this is on the list of upcoming CUs.
thanks in advance.
