Does lpd have to be running?

> I'm new to CUPS and confused.  CUPS is a spooling system, as is the LPD.  I've read questions that suggest that LPD might not be used in favor of CUPS; however, the CUPS documentation regarding command line printing references the lp and lpr commands.  If I shutdown the LPD, then lp and lpr do not work, and diagnostic messages suggest that I check to assure that the main LPD is running.

You need to use the versions of lp and lpr that are distributed with CUPS, rather than the default ones.

Are you on Solaris, Linux or some other Unix Variant?
