I have a program that will only print to a LPT port. To make this easier on
the user I wrote a script checking for the default printer adding another
printer with the same driver that uses LPT1. Then I capture LPT1 to the
iPrint printer using iCapture. However, I get the following error:

Printer 'dwd-ic-111-hp5500dn-cl' is not an installed iPrint printer on this

If I use the gui interface I can capture the printer and it shows it using
the iCapture show:

C:\>icapture show

Ports Captured to iPrint Printers:
LPT1: dwd-ic-111-hp5500dn-cl
Status: Printer responding

Anyone have an idea of what's going on here?
