No that's $1, but this script has &1 meaning file descriptor 1 (
standard output )
should be used as a duplicate input. I've never used this but i
suspect it's
just a way to kill any output from slp if any so it doesn't appear in
the printout.
Err: It does indeed kill output but not from slp but from the printer!
Printers today are often connected bidirectional and it may acknowledge
the commands by some OK message.
To kill ouput from slp you'd use
slp ... > /dev/null
instead.
( If slp did read from standard input it would get the answer this way
but it doesn't - if it did it would consume (part of) the printout too. )

cat - just forwards standard input to standard output.

When printing to our legacy Printronix P300 printer on our HP-Ux

I need help understanding what the "<&1" does and how it all works
with "cat
-".
That way, perhaps we could get the printer to work as a shared network
device.
Suggestions would be appreciated.
