For completeness, I will answer my own email with the solution I found.

I admit to having installed and un-installed various fonts a few times prior 
to the printing having problems.  I did not think I did anything wrong but I 
did do some of it outside of the usual KDE and Red Hat supplied utilities.  
Evidently I had messed something up in that process.

Further testing showed that KGhostview, a PDF and PS viewer that uses 
ghostscript to render things, could display some documents, but not others.  
None would print, all giving the fount not found errors in 
the /var/log/cups/error_log file.  Following the Ghostscript documentation 
for fonts, everything looked right but nothing would print.

In the end I took the brute force approach.  I exited all instances of KDE and 
got to a standard terminal.  I used 'apt-get remove ghostscript' which 
removed 39 (!) packages along with ghostscript.  Many very important ones.  I 
was nervous.  Then, I used the reverse command, 'apt-get install <all 
packages>' with all 39 of the packages that were removed on the single 
install command line.

After that completed sucessfully, I started up X and KDE and printing worked!  
Fixed.  I told my wife that I am a genious.  Then I confessed that I somehow 
had messed it up to begin with.  I tinker too much for my own good, 
sometimes.
