This is sort of urgent issue because customer is on the phone. He has several printers, he is able to print data from our software to these network printers no problem with the exception of one Lexmark T520 PS3 printer. When trying to to print it keeps telling him "There is nothing to print" and he isn't doing anything different than what he using for the other Network Printers. I'd like to find the IP address of this printer and was wondering is there a command that I can use at the DOS Prompt that will allow this or show all printers on his network and their IP addresses? I'm unable to go into Ports>Configure to see the IP address, it will not let me.
