The Microsoft Print to PDF printer does not have an ability to automatically name PDF files.  The user must manually enter in a name for each document they print.

 

The Win2PDF Print to PDF printer, however, does default to a name (the name of the document being printed) and it allows the PDF files to be automatically named and saved without any user intervention.

 

To automatically save PDF files without prompting, you can turn on the Win2PDF Auto-name feature.  This is enabled by first selecting the PDF Options... button on the Win2PDF file save window.  Then, navigate to the 'Document' tab and you will see the following checkbox for Auto-name Files.

 

 

The path used by the Auto-name feature is inherited from the currently selected path when you click on the "PDF Options" button in the file save window. To change the auto-name path, go back to the file save window and browse to the desired folder before clicking on the "PDF Options..." button.

 

 

To stop the Auto-name option, either hold down the shift key when printing to the Win2PDF printer, or run the "Stop Win2PDF Auto-name" program from the Start menu.  When you save the options, the following window is displayed:

 

 

 

 

Once Auto-name is enabled, you will no longer see the Win2PDF file save window when you print.  To turn off the Auto-name feature and resume prompting for the PDF file save, you will need to either hold down the SHIFT key when printing to Win2PDF, or go to the Windows Start menu and go to the Win2PDF program group.  There, you will be able to select 'Stop Win2PDF Auto-name', as shown below.
