Workaround found, but bug remains:
I used my Windows box IP address instead of Browsing for the printer. This permitted me to go to the next steps and created a printer, although it didn't work, i.e. the test page didn't print. However, I then clicked a change URI button and it presented another opportunity to Browse. This time browsing found the Windows printer, correctly changed the path and then the test page printed. Screen snapshot is attached.
