How do I connect my printer, wirelessly, to my laptop? -

I have an hp photosmart 7150, a Sony VAIO computer and a dell inspiron laptop.

OK listen and listen good, this could get confusing. I am assuming that you have a wireless router, if your router is next to your printer, get yourself a print server, plug the printer into the print server, and the print server into the router. If your router is not next to your printer, get a wireless print server, same rules then apply.
