Check Ink Levels

Query the HP DeskJet 5200 via IPP and report cartridge levels.

Read Printer IP

Read context/printer-config.md to get the current printer IP. If the file doesn't exist or the IP is blank, tell the user to run /find-printer first.

Query Ink Levels

Create a temporary IPP test file and query the printer:

cat > /tmp/hp5200-ink.test <<'EOF'
{
OPERATION Get-Printer-Attributes
GROUP operation-attributes-tag
ATTR charset attributes-charset utf-8
ATTR naturalLanguage attributes-natural-language en
ATTR uri printer-uri $uri
ATTR keyword requested-attributes marker-names,marker-levels,marker-colors,marker-types,marker-low-levels,printer-supply,printer-supply-description,printer-state-reasons
}
EOF

ipptool -tv ipp://PRINTER_IP:631/ipp/print /tmp/hp5200-ink.test 2>&1

Replace PRINTER_IP with the IP from config.

Parse and Display

Extract from the IPP response:

Field	IPP attribute
Cartridge names	marker-names
Levels (%)	marker-levels
Low thresholds	marker-low-levels
Supply detail	printer-supply (parse level= values)

Present results as a clear table:

Ink Levels — HP DeskJet 5200 (10.0.0.72)
─────────────────────────────────────────
  Tri-color (CMY):  ██████░░░░  10%  ⚠ LOW
  Black:            ███████░░░  30%
─────────────────────────────────────────

• Show a warning indicator when a cartridge is at or below its marker-low-levels threshold.
• Use simple block characters for the bar (█ for filled, ░ for empty, 10 chars wide).
• If the printer is unreachable, suggest running /find-printer.

Cleanup

rm -f /tmp/hp5200-ink.test
