OK, now I understand the problem.

You have installed a third party PDF printer driver on your computer, called PDF Complete. I have no idea how it works, but I would imagine that there is a setting in the utility where you can ask it to prompt you for a location in which to save the PDF file.

This PDF Complete printer driver will use the cmthsp.enz form file, just like any other physical printer driver. Only Pastel's in-house PDF option will use the cmthpdfsp.enz form file.
