In the user interface, there is a small button that will remember where you previously saved your PDF files.

If you click that button, it will bring up a list of Recent Save Locations.

The printer stores the recent folders in a user.ini file under the user’s %APPDATA% folder.
Here is a typical location of this file:
C:\Users\USERNAME\AppData\Roaming\PDF Writer\PRINTER NAME\user.ini
The content of the file is shown in the box below. The lastfolders setting is a list of folders separated by the | (pipe character).
[User]
lastfoldername=C:\temp\
lastfolders=C:\temp|C:\Users\jacob\Dropbox\
lastoptionsetname=
lastoptionsettype=private
