There were no lines in the file that were un-commented, so my 2 lines are the only things being read.

> I think you don't exactly understand file permissions. So I will

I've been using *nix systems for 4 yrs, but sometimes things get confusing.  :)  This version of CUPS is making me pull my hair out!

> What I try to explain is that only root can read/write this file. --> You have to change the permissions!

The point I was trying to make was that if I am operating as a member of the wheel group, then I should be able to read and write to files that are owned by the wheel group.
If Group wheel is set in cupsd.conf then when it needs to read or write to /dev/lpt0, I would think it would be able to, because /dev/lpt0 is owned by the wheel group.

I saw an error in the error-log:
I [01/Jul/2006:11:52:52 -0500] Loaded configuration file "/usr/local/etc/cups/cupsd.conf"
N [01/Jul/2006:11:52:52 -0500] Group and SystemGroup cannot use the same groups!
I [01/Jul/2006:11:52:52 -0500] Resetting Group to "nobody"...

I commented "SystemGroup wheel", still not seeing printer in Mac printer browser.
I currently have the following in cupsd.conf:
