ksh - can use read with pipe:

lpstat | grep "^abxxxxb1 " | read queue dev status somefields

[ "$queue" = "" ] && print "no status for abxxxxb1" >&2 && exit 1

[ "$status" != "DOWN" ] && print "abxxxxb1 ok" && exit 0

print "abxxxxb1 is down"

General sh version to use read:

read queue dev status somefields <<EOF
$(lpstat | grep "^abxxxxb1 " )
EOF
