lpadmin -d <printer> is ignored

[ekkard gerlach]

I tested  lpadmin -d <printer>   on two Suse8.2 machines
but the command is alwas ignored. The command seems to be
accepted (no message/ error reported) but lpstat -p -d
reports: no system default destination

pserver:~ # lpadmin -d laserpr
pserver:~ # lpstat -p -d
printer eps570rosset is idle.  enabled since Jan 01 00:00
printer laserpr is idle.  enabled since Jan 01 00:00
printer test is idle.  enabled since Jan 01 00:00
no system default destination

I tested lpstat -d on two different machines. Where is
the error?
