i can change my address online through online backing but im with barclays so it might be different with other banks.

and about the printer, it depends whether u work more in the library or at home. i work more at home so i prefer to have my own. its also helps that u dont need to go all the way to library when u need to print just a page or something. like someone said, the ink cartridges are not cheap (2 of them can buy u a printer), so try not to waste any.
