Printing in Gnome via the serial port

[James Flanagan <nezeray home com>]

I'm new to the list so please be gentle. ;']

I have Red Hat 7, with Gnome installed.  I don't know what version right 
off hand.

I'm trying to setup my Linux box to print over any/all of the possible 
ports.  The only port I haven't figured out is the Serial port.  I'm 
printing to a Lexmark Laser printer so the language isn't a concern.

The main thing I need to know is how to setup Gnome <or RH linux> to print 
over the serial port.  I've been told that Com1 's Linux equivalent is 
ttyS0.   How do I set the baud,parity, and data bits?  For what I'm wanting 
to do with the serial port I need to be able to change these to match the 
printer.

I appreciate any help you can give me!  even pointing me to the correct 
how-to would help.
