First off, I've just bought an Epson R300 printer. What a machine! It prints beautifully, quickly, reads all memory cards, and prints directly on printable CD's and DVD's. A bargain at £129 I'd say. Anyway, been reading the manual and it talks about a portion of ink being used up when the printer is switched on. So if like me, you print an occasional document and switch the printer off afterwards, your just wasting ink! So is it a good idea to leave your printer on 24/7 just for the occasions when you actually use it? Surely this would make your ink last loads longer!
