Welcome to the forum.


I'm not sure I can follow your specification, as it sometimes seems to

- contradict your sample code / output (e.g. "no kills the spooler PPID "11814"" - are you talking of the process ID or the parent pr. ID?)
- refer to data NOT in the sample: 72:00:00
- use non-existent options (-e to pgrep; not found for pgrep on linux nor FreeBSD, only for pkill)


SHOULD you want to kill the processes that are childs to the lp root / parent process identified by PPID = 1, try

Code:
ps -eaf | awk 'BEGIN {printf "kill "} /lpsched$/ && $3 > 1 {printf "%s ", $2} END {printf ORS}' 
kill 22948 19332 29793 18598 26198 24981 13996 5802 24510 4585 26585 25739

If happy with the result, pipe the output through a shell (append | sh), or source it using "process substitution".
