No, that's to allow Windows file shares to be mounted on the tablet. If you combine CUPS and Samba in your chroot, you can print to Windows printers.

Funny, I have two laser printers. I use each of them maybe once a month or less. I'd install printing support on my N900, but I just don't need it. I checked onto a flight last September, just showing everyone the screen of my N900, which had the big boarding pass barcode for scanning... Didn't even need a paper boarding pass...
