You mean e-ink? http://www.eink.com/

What do you mean by "digital paper"?  Or, in other words, what
features do you want?

Several companies sell Bi-stable Cholesteric displays that keep their
contents after power off, but are different than E-Ink type displays
in a variety of ways.

E-Ink does have "stock" sizes and parts, but they are still rather expensive.

If you don't care about power consumption, then why not a regular cheap LCD?

Define "large display areas", "expensive", and what type of
information you are displaying (graphics, text, numeric, etc).  Is a
display with multiple LCDs panelized ok, or does it have to be one
contiguous display?  Are existing 'cheap' LCD TVs too expensive?  If
graphical, what are the resolution requirements?

My understanding is that large digital paper displays are more
expensive than LCDs at the moment, and generally only used where
higher durability, low power, better readability, or no power to
display static content justifies the additional cost.  Only in mass
quantities and highly integrated embedded devices (ie, consumer e-book
readers) do the costs of E-Ink and similar drop down to below that of
LCDs

If by "rather" you mean extremely - their 6" prototype kit costs $3000

What sort of resolution are you after?  As far as I know, this is NOT  
the sort of market that "digital paper" is currently addressing.  
Aside from the Esquire e-paper cover demo, most e-ink displays are  
aiming at actual high-resolution paper replacement, where the  
electronics and electrodes are significantly complex compared to the  
supposedly mass-producible display material itself.  I'm not actually  
aware of any "very large display area" technologies; aside from  
macroscopic magnetic things, and assorted projection and/or lamp/led-
based things...

Laser printer. Used are dirt cheep. Uses lots of power too.

CO2 laser set to low power, with scanner mirrors - slow, lots of
power, but potentially expensive.

I wasn't paying attention what the OP wanted or what his capabilities are.

Would something like a giant Etch-a-Sketch be what you are looking for?  You
would have to make an interface to the mechanical components.
