Error: The document I have published has printing enabled but the print icon is disabled in the viewer

Check that the document has not got standard Acrobat password security set on it and that printing is allowed.

If you have a permissions password set on the document and have disallowed printing, then the Safeguard viewer will honor those settings even if you protect the document with printing enabled.

If printing is disabled on the PDF document you must remove these settings before protecting the document.
