First, Adobe Acrobat (the full version, not the reader) must be installed on the workstation. If your user selects from the printers (start, settings, printers in Win98) the Adobe Acrobat "printer" (acrobat distiller) BEFORE asking Access to print the report, the creation of the pdf file will be handled properly.
If this is something that will happen frequently, you might want to include some pop up message as part of the printing functions that remind the users to select the acrobat printer first.
Does anyone know of a way to give the users an easy way to select the destination printer from some code within Access (so the users' options and menus are very limited)?
