1st order of business, don't top post.
Also, linux isn't like windows. It has the ability to handle multiple
users. You can create a user for your laptop to connect and print
with. It's really simple.
My diagnosis (I've been watching nip/tuck) is to add a user for you to
print with. I might be completely off though, I don't ever print with
computers and printers.
