>I cobbled together a short PRG from several examples I found here at the UT to test sending faxes using the MS Fax Printer. Everything works till the send then I get the error (see code). I checked and the REPORT.TIF file can be opened in MS Paint as a .TIF file and it looks ok.

Hi John,

It's not clear where the problem is. To narrow it down I would try to send tiff file created by some other method to see if faxing code doesn't work or VFP creates "incorrect" file.
