I agree with Alexander. Having six separate specialist devices is preferable to a multi-function printer scanner and having a designer mockup your web pages and then have them hand-translated to HTML by a HTML specialist is definitely the route of choice.

Sadly many of us don't have room to accommodate all this stuff, or people, or the budget they require, so a compromise is in order. XWD is that compromise. I would agree that XWD does not make a good multifunction printer/scanner.
