OK. I got it running with

/sbin/service cups start

OK - I used killall -HUP cupsd

Yeah - I chose LPRng (default) - I thought it was one of two CUPS - why would
CUPS cinfiguration offer LPRng when it is not CUPS?

bash: alternatives: command not found

[root-5jgDBJOV2nY at public.gmane.org lsf]# /usr/sbin/alternatives --display print
print - status is manual.
 link currently points to /usr/bin/lpr.LPRng

OK.

/usr/sbin/alternatives --set print /usr/bin/lpr.cups

OK.

[root-5jgDBJOV2nY at public.gmane.org lsf]# /sbin/service lpd stop
Stopping lpd:                                              [FAILED]

It did. I'm printing with CUPS! Thank you. I'll keep hard and soft copies of
this email. Printed with CUPS, of course.
