>From VFP you print the report (I assume you mean PDF, not TIFF) using REPORT FORM just like you would print to any other printer. There is some code at http://fox.wikis.com/wc.dll?Wiki~UsingAmyuniPDFConverterWithVFP~VFP that might be helpful.Yes, the converter installs itself just like a printer driver.
Note: Whenever you link to the Fox Wiki, don't include the namespace, i.e. the last "~VFP" in your example. Otherwise, if the namespace changes, the link is broken.
