I've been looking at the HP one on the PC World advert:</p> http://www.pcworld.co.uk/martprd/product/seo/070226 </p> If I connect to it wirelessley, does that mean that i can or can't be connected wirelessly to the internet at the same time? </p> Also, is there such a thing as a bluetooth printer, that I could send things to print from my laptop vis bluetooth? </p>
Your wireless printer will have an IP address and appear on your network, you will print to it as a network printer, your Internet will work unaffected.
I've only used a Canon one but the principle I'm sure is similar. The printer connects to your wireless network just like your PC does. So it isn't a case of you disconnect from your router (and therefore internet connection) to establish an exclusive wireless connection to your printer. The data sent for printing goes PC->router->printer. And yes there is such a thing as a bluetooth printer but I've never used one.
