Did you look for information on setting up your printer at
http://www.linuxprinting.org
Printing in GNU/Linux makes use of a printer server. The 2 common servers are CUPS and LPR, most likely FC3 makes use of CUPS.
You may need to look on the CUPS webpage for more information on setting up your printer.
Is this a newer model printer? USB or Parallel port printer?
If it is a parallel printer, did you test the printer to see if it would print via the command
ls > /dev/lp0
url correction made, thanks for pointing that out.
