Fernando,
do you mean how well does it work? Pretty well, in our experience. All you do is perform a REPORT ... TO PRINT after having set up a printer driver in Windows which points to the PDF *convertor* (the creator wasn't released the last time I looked). You shouldn't have to change your reports at all, unless you want to try some fancy stuff like generating PDF bookmarks at section breaks, for example. Try this link for some more documentation
http://www.amyuni.com/support.htm#downHere's a little sample code from our app
SET PRINTER TO NAME "BRITEPDF"
DefaultFileName(this.PDFHandler, this.outpath+this.outfile)
FileNameOptions(this.PDFHandler, 1+2+32+iif(this.concatenate,4,0))
REPORT FORM (p_ReportName) NOCO NOEJECT TO PRINTER
SET PRINTER TO DEFAULT
Best wishes,
Neil
