Vista - Adding Adobe PDF-Online web-based printer

Any ideas on how to add a printer for Adobe PDF online?

In XP, you could "Add a network printer", and use the http address for the
web service - typically "https://pdf.adobe.com/cpdf/Printer?id=xxxxxxxxx".
This added the printer on an Internet port.

When I try this in Vista Ultimate, I'm not able to do this.

First I tried to use the "Add a network, wireless or Bluetooth printer"
option, followed by "The printer I want isn't listed". The "Select a shared
printer by name" option allows me to use the https address, but reports
"Windowes cannot connect to the printer. make sure that you have typed the
printer name correctly, and that the printer is connected to the network".
The "Add a printer using a TCP/IP address or hostname" option then lets me
select "Web Services Device" in the Device type dropdown, but then the
Hostname or IP address field will not accept the "?" character of the printer
URL.

Second, I tried to use ":Add a local printer" then ctreate a new port as
"Internet port"; however the only port types allowed are "Local port",
"Microsoft Document Imaging Writer Port" or "Standard TCP/IP Port". The last
looked the most promising, but again I was not allowed to enter the URL.

Does anyone have any ideas about how to set up a web-based virtual printer?

Thanks,
D.
