network printing

[gerhard]

I screwed up my /etc/cups/cupsd.conf file while trying to install a
network printer. Can someone send me a copy I can paste in here. If I go
to System=> Administration=> Printing.....the screen does not pop up so
that I can not set up the printer.
I got a HP Deskjet 1220C connected to my Ubuntu box and my wife got XP
on her pc but we want to use both this printer. I got ADSL rooter with
ethernet connections to both PC's......will this do as a network between
the 2 PC's as well???
Followed all the instruction on the Documentation and Community section
but no luck
Can someone please help??? anyone also experienced automatix2 update
problems???
