I have an HP DeskJet 6540 shared via a US Robotics US809108 ADSL router at
address
http://192.168.1.1:1631/printers/My_Printer. I can connect to the
printer, and print successfully from a Windows XP machine, yet when I try to
connect to the same address from Windows Vista I am told:
"Windows cannot connect to the printer. Make sure that you have typed the
name correctly, and that the printer is connected to the network."
Adding it as a local printer and then assigning the port
http://192.168.1.1:1631/printers/My_Printer doesn't work either, test prints
just sit in the queue.
