The program 'lp' is set[ug]id to user 'lp' and that's why...

	lp < file
also works, [as was pointed out], but only ONE file at a time can be queued.
Now for the solution.  Over here we use 'llp':

	llp -dclaser -ob -og -t1+2 file1 file2

'llp' understands all 'lp' options.  In fact 'llp' just passes
its options on to 'lp'.
'llp' takes multiple file arguments, concatenates the files,
each separated by a formfeed, and the resulting output will be
standard input to 'lp'.  Only one queue-id is used.

SYNOPSIS
  llp [lp-options] [files]

#-------------- snip 8< snip 8< snip --------------- BEGIN
#ident "@(#)llp.sh	(a3)	1.0	17 nov 1988"
# Usage: llp [lp-options] [files]

for arg
do
  case $arg in
    -*) shift;;
    *) break;;
  esac
  case $arg in
    -o*)
	t=	# take special care of white space
	for i in $arg
	do
	  if [ -z "$t" ]; then t=$i; else t=-o$i; fi
	  oopt="$oopt $t"
	done
	;;
    -t*)
	topt="$arg";;  # take special care of white space
    -*)
	mopt="$mopt $arg";;
  esac
done

# If there are no filearguments, use the standard input.
if [ $# = 0 ]
then
  cat
else
  for file
  do
	[ -n "$cat0" -a -z "$cat1" ] && echo "\0014\c"
	if cat "$file"
	then
		cat0=0
		cat1=
	else
		cat1=1
	fi
  done

  lp ${mopt} ${topt+"$topt"} ${oopt}
