solving printer offline problem

I have had a problem with epson printer, it is networked and on 1 computer keeps going offline but works fine on another. I was able to ping the printer from both machies . I went to PORTS under printer properties and noticed that on the printer that didn't work the port address that the printer was under was same but with _1at the end and clicking on the properties i noticed that the printer IP address was wrong. I changed it to the correct IP address and ther rpinter came online.

Until someone with more experience in this comes along - I'd suggest uninstalling the Epson software/drivers from the problem machine. Then download a fresh copy of the software/drivers from the Epson website and install that.
