Digital BW, The Print

I'm PC user printing on Epson 7880 from Photoshop.

Lately watching training video I've discovered that Lightroom allows 16-bit printing under Mac OS X 10.5 

I've made some research trying to figure out if windows Vista 64 can print in 16-bit. I've found a document that says yes, it can, here is the link:

But then I've called Epson tech support and the guy told me that Windows driver is 8-bit, there is no plans for 16-bit driver for Windows 7 because it doesn't support 16-bit printing.

So now I'm thinking to replace my PC laptop with Macbook. I still want to work mainly on PC in 16-bit, but when image is ready copy it to Macbook and send it to the printer through Lightroom in 16-bit.

What do you think? Does it make sense?

Thank you,
