something sounds wrong here...

cd /usr/share/cups/model
ls -l HL2140.ppd lp3.ppd
are both files there? root:root? 644?

they don't need to be gzipped

diff -u HL2140.ppd lp3.ppd
I'd be interested in that output

My thinking is that cups is pretty forgiving on format of those files
(i.e. Windows or Macintosh line endings probably don't matter)

If the only difference between HL2140.ppd and lp3.ppd is really the
'DefaultPaperSize' kind of thing, you can set that up in 'Printer
Options' and just use the HL2140.ppd as it doesn't make sense to me to
have different PPD files for things that are controlled in 'Options' -
perhaps this is the resultant files in /etc/cups/ppd/ directory you are
describing...don't put files there manually because I think that will
cause issues with both cups and selinux.

/etc/cups/cupsd.conf went on a diet somewhere between F8/F9 as I
recall...

On F10, the entire contents of my /etc/cups/cupsd.conf is... (for
comparative purposes, lines will break)
