Rewrite of the Handbook Printing chapter

[Warren Block]

The existing Handbook printing chapter has many weaknesses:
   It does not cover simple setup well.
   It does not cover current devices well.
   It uses some confusing terminology and shows examples for uncommon
   situations.

I've complained about these problems before, but a few months ago, Dru 
asked me to do something about it.

This is a from-scratch rewrite, attempting to address the major problems 
of the old version.

It adds a quick-start section, simplifies setup, vastly reduces the 
section on shared printers in schools and businesses, and provides a 
framework that allows the addition of other printing systems.  The first 
candidate for that would be CUPS.

Initial responses have been good.  If there are no showstopper 
complaints, I plan to commit this in the next week.

Feedback and testing welcome.  Thanks!
