I have a printer on a network that I can manage remotely using the host name of the printer. Today I saw several jobs hung in the print queue and I tried restarting it via host name. I could not access the printer nor could I ping the host name. I had someone on site take a look and he was able to get the IP address and I could access it that way but all of my printers are set up by host name. What would cause me to be able to ping the IP address and not the host name?
