suzanne,

does your printer have a slot where you can put in a memory card? I think that might be the reason that it is seeing it as a storage device. If so is there a card in there? You could try taking that out, might or might not make a difference - I've never used an HP printer always have epsons myself, but all printers can be temporamental!

Epsons have an inbuilt system which after a certain ammount of printing will tell you it requires maintenance, and refuses to print, most people at that point get a new printer, when infact it just needs a reset, which you can find stuff for online, or a local printer shop will do it for you for around £15 - way cheaper than a new printer - i only found that out AFTER shelling out for a new one! typical! lol
