This past Friday I finally submitted my PDF and received this response from the printer:

Thank you for submitting your book, “The Artist on the Road,”  on Dec 04 2009 PT. We will review your files and book information and notify you of the results via email shortly, typically within 24-48 hours.

Over the weekend I Recieved another message that the files have been approved for printing. Now I’m impatiently awaiting my proof copy from UPS.
