[Tuglist] unable to access epson stylus colour 480 in linux

[Dr. S. Biswas]

I have got 7.1 Redhat linux loaded. I am unable to access the epson 
stylus colour 480, though epson stylus colour 460 is in the menu list. 
As instructed everything is done /dev/lp0 is detected, test page printed 
command is also shown but the printer does not respond. Can anybody help me?
  In the same computer I have winShell in window platform. It was also 
uanable to print ps files. After loading ghostgum, GS 7.0 epson stylus480 
now prints ps files.
What is the trouble with the linux?
