Back in 2004 I've read a quite interresting article on ARM. http://news.cnet.com/The-unheralded-monopoly/2010-1006_3-5262581.html As you can see, the strong position of the ARM is not new, maybe just a bit more visible these days.

Why would you by a "web printer" if at the same time you want to block its access to or from the internet? Let's just see what we are talking about here: - the is a printer whose purpose is to allow direct printing from the web - the direct printing from the web is done through the HP ePrintCenter which is a service hosted by HP and which accepts the print jobs. - your printer merly connects to HP ePrintCenter to pull jobs from there are do any other tasks it is being told to do So if you in any way block the access from your printer to HP ePrintCenter, then you effectivly block your pritner's ability to print (or at least to use the web printing, I don't know if these printers can also do local printing), and in that case, why did you buy this printer in first place?

I guess you misunderstand how these printers work. HP has an internet platform called HP ePrintCenter. Jobs from other sources are sent to that HP site and your printer pulls the jobs from there. So no one will try to connect directly to your printer, but your printer will try to connect to the internet to find jobs to print.
