I am using LabVIEW 7 on windows NT4 computers. I have a SubVI that I use to ping the network printer to make sure that the printer is on line prior to sending a print at the end of testing a unit. If LabVIEW does not get a reply to its ping data is saved locally and the user informed. I would like to modify the VI that pings the printer to ping the default printer of the computer on which the VI is running. I would be grateful if anyone can show me how to retrieve the default printers IP address.
