Um, where are you seeing this error?  The CUPS lpr command will never  
try to reserve a port, and with 1 printer you should never see the  
CUPS lpd backend produce it, either.

FWIW, port reservation tries to use a privileged port (< 1024),  
however NFS and other system services will use up many of them.  LPD  
normally uses ports 721 through 731 as "source" ports (515 is the  
destination), so if none of those ports are available (because other  
processes are bound to them - "netstat -an" will show them) you won't  
be able to print via LPD with the default settings...
