backend $6

[Jim]

My backend script used to get %6 on a regular bases.
Now it is never passed.

I can still catch it with:  cat > "$copy"

Is their some setting that controles the passing of $6 for backends?

Also, if I set: LogLevel debug (in cupsd.conf)
It shows:
StartJob:
argv = "sharp-01","52","root","51","1","","/var/spool/cups/d00052-001"

from backend:
echo "There were $# arguments on the command line.">>/tmp/log.txt

Only 5 arguments are being sent.

Any idea what is going on?
