DNS server list setup question

[Labitt, Bruce]

I'm sorry if this is a malformed question...  In which file does one set
up the list of DNS servers for a linux box?

I'm adding a network printer to my computer.  I was unsuccessful for a
while.  I did note that I could ping the print server on my windows
computer, but not on my linux computer.  In which file do I add the
additional company dns servers?

Thanks!
