Printly

Printly detects your Whatnot auction wins in real time and instantly sends them to your thermal printer — no pausing your show, no scribbling on notepads, no missed buyers. HOW IT WORKS • You go live on Whatnot as usual • The moment a buyer wins, Printly catches it • Your label prints automatically — before the confetti clears WHAT YOU NEED • This Chrome extension (you're here!) • The Printly Print Agent — a small background app that drives your printer (free download at printlyapp.me) • A Printly account — start free with 200 labels, no credit card required FEATURES • Instant win detection via real-time WebSocket monitoring • Works with any thermal printer (Dymo, Zebra, Rollo, MUNBYN, and more) • Auto-print or manual mode — your choice • Live dashboard to track every win, buyer, and print job • Custom label sizes: 4×6, 2×3, 1×3, and more • Add your logo, seller name, and accent color to every label PRIVACY Printly only activates on whatnot.com.
