How do I print from my laptop to my main computer's printer - Campli

Ok, I know you've probably seen this question many times but I seem to have
something quirky going on.  I have a main computer in my home office...not
networked.  It gets to the web via a linksys modem in which my laptop or any
other wireless computer near the modem can get to the internet.  What I'm
trying to do is to share my main printer so my wireless laptop may print to
it.  I've set up the printer as a shared printer with the name of EPSONSty.
I've gone to the laptop and tried to locate the printer and it's not showing
up...I must be missing something here.  Please help.
