Canon LBP6000 / LBP6018 (i-SENSYS 6000)

Does ANYONE know why the driver I downloaded from Canon (CAPT _V320_MacOSX_ukEN) will not run my Canon LBP6000/6018? Seeing as the Canon HK website (my local) told me to go there to download it and it SPECIFICALLY SAYS it's for Mac (10.4 - 10.6)?

I'm absolutely raging. D**m thing cost me HK$1,000 (US$127.00) and I get home to plug it in and find that nothing remotely like my model name is in the drop-down list in the printers pane. After downloading, installing and even - GASP - restarting my iMac, there is still no mention of it or any way to choose anything vaguely similar to my printer.

I'm not a computer bod and I don't know what I'm doing, but I'm on the verge of calling Canon and tearing them a new one (as it says ON THE BOX that the printer is compatible with Mac). 2 hours arsing about with hundreds of obscure websites to find a driver to replace the one that doesn't seem to work from the manufacturer? Unacceptable.

Any hints or help at all would be appreciated. I actually bought the thing to print with tonight, not expecting any installation problems. I have never had such trouble with any other peripheral/extra I've bought for my Macs since 2002.

Thanks anyone!
