The PDF printer should not be configured to LPT1 but to a defined Adobe PDF Port Monitor.

Go to the printer and right click and select 'Printer properties"
in the printer properties window click on the ports tab
scroll through the list of printer ports and see if there is one with the description of "Adobe PDF"
if there is none then click the "Add Port..." button
in the printer ports window select the "Adobe PDF Port Monitor" and click the "New Port" button
you then need to select a folder to place the PDF you will create (ie. my documents, or desktop)
once you have finished this you should now see a new port in the window listed as the folder you selected \*.pdf (ie: desktop\*.pdf)
make sure this port is checked and click the OK button

now trying printing to this PDF printer again

Apparently, many Windows 7 users found that the Adobe PDF Printer port was not even created during install.
If that is the case, follow  silverkorn's instructions; but choose add on the port tab and navigate to the Adobe folder to add the port.  Mine is in C:\Program Files\Adobe\Acrobat 8.0\Acrobat\Xtras\AdobePDF

Lpt1 is a local port.  If your printing to a network printer configure it in settings.  You may have to get your admin to install the driver.
If it helps here's a youtube video
This video shows you how to install the PDF driver.
