Looks normal to me. Do you have the latest cups appropriate for your
FC4? (yum update cups).
(Creating this prompt on Mon Aug 07 at 15:55:52.)
# yum update cups
Setting up Update Process
Setting up repositories
Reading repository metadata in from local files
Could not find update match for cups

I suppose that "\|" in your suggested command translates to OR . I use
bash on fc4. If it was supposed to do something different than what I
supposed, tell me and I'll retry.
No, you were "supposed to" type both of the characters '\' and '|', but
it doesn't make any difference because you improvised correctly to run
two commands (one with cups, one with lpd), and confirmed that cupds
_is_ running and there is not any lpd running.
I didn't "type" anything. I used cut and paste to put your command (as
*you* typed it) directly to the bash command line. It didn't work, so I
/surmised/ that the '\' was escaping the '|' to allow it to mean "OR" to
allow a dual search in one shot.
Interesting(?) aside..
My format,
grep cups\|lpd
was intended to check for either match in one call, but my advice was
wrong anyway -- I should have used egrep, because grep doesn't do
alternatives (egrep does). I should have said
egrep cups\|lpd
or equivalently
egrep 'cups|lpd'
The significant point here is that '|' normally has special meaning to
the shell, and either the '\' escaping or the '...' quoting prevents the
shell from interpreting special characters.
As I surmised.
