WinFax Pro does not support Windows 7.

PlanetPress documentation indicates use of Windows fax is supported. I saw that Win 7 fax is supported in one of the newsgroups postings (posted by Phillippe F on 21-Feb-2014 at 11:35 AM).

How is that done. Win 7 fax requires information be entered for each fax individually, there is no documentation that I can find on how to automate it and pass the fax number and document to it.

Jacob,

The fax number must be set in the Planetpress Design Document using the data selection object.

Here is a link: http://help.objectiflune.com/en/planetpress-design-user-guide/Default_CSH.html#/1336.html

Then in your workflow, use the PlanetPress Fax connector. You must do some settings prior to that in PlanetPress Fax user options

Hope this helps.
