>>>I'm using the API to change my default printer to "Acrobat PDFWriter" so that I can print a report to a pdf file. Everything works great in NT. When I try in 95 I get the error "printer not ready". If I add the prompt keyword to the command, the print dialog comes up, you hit ok and the report is printed to a pdf file. Is there a way to get this to work in 95 without the dialog.

OK, let me ask you this: You say you're using the API to change the default, right? If so, then you're using WriteProfileString() to update the WIN.INI file, by setting the device entry in the Windows section. So my question is: Are you using SendMessage() to broadcast the change to all top-level windows?
