This may be a simple question but still. I currently have a laptop connected to an ADSL modem via a standard RJ45 cable, and also to a HP LaserJet 1300 via USB. I have now purchased a Dimension 4600, which I would like to connect to all three devices. In other words it would be good to have both computers connected to ADSL (independently, so no Internet Sharing), to each other so that I can access files when both are on, and also connected to the printer (again independently). The reason I want independent connections is that the laptop will be in and out of the office, and when it's in the stationary system will not always be on.

If I'm not mistaken the purpose of a router is to be able to interconnect several devices (though this may be the purpose of a switch too?). Therefore, will it suffice to get a router to connect both computers to each other and to the ADSL modem? Or do I need to get an ADSL router, thus bypassing the need for an external ADSL modem?

As for the printer, well the HP website says it's "network-ready" when you "use the USB/parallel port connection to add the printer to an office network environment." Now, how can I use a USB cable to connect to both computers; is there such a thing as a USB split cable, or is there an easier solution?

I would appreciate feedback on this dilemma, and also a recommendation on which router is a good, and not too expensive, choice.

Thanks in advance.
