Experimenting with media-ready for the paper level.

Not had a chance to test this yet, so for redundancy:

diff --git a/home/scripts/printer-toner.sh b/home/scripts/printer-toner.sh

-echo "Printer toner: $n% remaining"
+toner_perc=$(echo "$data" | grep marker-levels | cut -d = -f 2 | xargs)

+# Don't know if this changes upon running out of paper, needs verifying
+if echo "$data" | grep -q 'media-ready (keyword) = iso_a4_210x297mm'; then
+  paper_available="Paper is available."
+else
+  paper_available="WARNING: No paper is available."
+fi
+
+echo "$paper_available"
+echo "Printer toner: $toner_perc% remaining"

Edit: No luck.
