I am asking all you OS X proficient guys out there;
How do I do this.....?
(This question may be similar to questions asked
here but I need a step by step guide since I am
not a computer tech.)

I have an IMAC G3 running (OS X 10.1). I have
successfully connected
to a LINKSYS wireless broadband router (
BEFW11S4) via a DSL modem
to DSL telephone line service. I am hardwired to
the router.

This was done so that I could have my DELL
Inspirion laptop running (Windows XP Home) talk
wireless to the router in the same (home office
set-up). I can connect to the internet with both
computers without a problem, thus it is connected
properly.

NOW here is the question. Can I setup the DELL
to print documents?
I know I must get the IMAC to share the printer, but
I don't know how to do that. I have a HP three way
all-in-one (HP PSC 750) and it is connected to my
IMAC through the USB port. It is hardwired to the
IMAC.

I want ,in the end, to be able to connect to the
internet using the DELL laptop or the IMAC, and
also to be able to print with either computer.

Once again, I need some step by step instructions
or a LINK to
a guide on how to set this up. I do not need to
share any kind of files
between the two computers.

THANKS in ADVANCE

look into samba for osX
that allows it to make windows shares for disks and printers

Under 10.1, it's extremely complicated (requires terminal hacking.) It's much easier under 10.3 Panther (There's a checkbox in the Sharing prefernces pane) If it is at all financially feasible, I would suggest you upgrade to Panther.

I have tried many options, the one that worked for me was
to get an ethernet adapter that allowed my printer to be
attached directly to my router. Then I just IP print off both
my windows machine and my mac. The adapter was only
about $40. I had invested much more in the time trying to
make it work with software, ie Dave. The adapter/print
server I used was DP-101P by D-link. Good Luck.
