Derek,
>report form myReport to file myName.prn
That will create a printer output file, for whatever printer driver is currently selected. So yes if you have Postscript printer selected it will create a file of Postscript commands. But that requires that the person recieving the file has a printer that can understand Postscript commands.
>This will simply print the document to a postscript file, which will contain all the BMP's, ICONS etc., etc. that appear in your report. However, these files can be large, especially if there are loads of BMP's. Run a test then check how big the file is.
