UUOC:

% /usr/local/bin/lp ~/MyPostscriptFile.ps

CUPS chose to use identical names for their printing commands. 
Sometimes people delete the system lpr (/usr/bin/lpr) so that only the 
CUPS version is found, or link one to the other.  The system lpr will 
come back if you rebuild the system, unless you take other actions. 
The CUPS article talks about this near the end:

There may also be options in your "desktop environment" preferences to 
select which printing system will be used.
