I'm setting up an old laptop for a friend (PII 300Mhz 128mb ram 4G hard disk - how quaint). I've put on a stripped down version of Windows XP with SP2 (has all drivers installed, but loads of non-essential stuff stripped out) which works fine on other computers. He's a bit careful with his cash (if you hadn't guessed from the laptop he bought!) and so I was extremely careful when I took him to buy a printer. We got a Lexmark Z735 and I've installed it, but half way through the installation stops and says the cartridge is unsupported... please install a correct print cartridge. I know for a fact it's the right cartridge so has anyone got any ideas why this won't go any further? I've checked that I fitted it right! Unless someone strongly believes it's a fault with the actual printer, I don't see the point of installing it on my machine as they're chalk and cheese in performance, and I'm not running the stripped down version of XP (and can't without a great deal of reformatting and repartioning) . Could I be missing a driver in this version of XP? If so what? Cheers!
