Rich,

Well, then it is not a VFP question. For Word and Excel documents I used sendkeys method to control the printer (however, most likely the code will differ for different printers.)
See http://support.microsoft.com/support/kb/articles/Q194/3/06.ASP for details.

Sorry if I didn't make my problem clear enough. There are no FoxPro reports involved. I am printing only Word documents and/or Crystal Report documents. I use CREATEOBJECT(word.application) for the first and a Crystal Report control on the form for the second.

How can I programaticly control which way the printing occurs??

Thanks again for all input........Rich
