How to Automatically Print Whatnot Labels (Mac & Windows, 2026)

If you run live shows on Whatnot, there’s a moment every seller knows: the show ends, the adrenaline fades, and a pile of unsorted items stares back at you. Automatic label printing deletes that moment. A small sort slip prints itself the instant each sale closes — buyer name, item, price, box number — so by the time you say goodnight to chat, every item already has a label sitting on it.

This is the full setup, start to finish. It takes about ten minutes, and most of that is unboxing a printer.

What automatic label printing actually is

Two different things get called “label printing” in live selling, and mixing them up causes most of the confusion:

• Shipping labels are the postage you buy from Whatnot after the show. Whatnot generates these; nothing else should.
• Sort slips are the small labels that tell you which item belongs to which buyer while you pack. This is what automatic printing produces — one slip, printed in real time, the second an auction ends.

Automatic label printing means the sort slips handle themselves. No exporting a spreadsheet after the show, no clicking each order, no handwriting buyer names on painter’s tape. The label prints while you’re already presenting the next item.

The three ways sellers do this

By hand — sticky notes or a spreadsheet, one entry per sale. Free, and fine until the first busy show; past that it’s slow and error-prone, and errors here mean shipping the wrong item.

A browser extension plus a print bridge — some setups hook a Chrome extension to a separate print utility. It can work, but it’s two pieces of software to install, keep updated, and troubleshoot mid-show — and mid-show is exactly when you can’t.

A dedicated desktop app — one native program that shows you Whatnot, watches your sales, and drives the printer itself. Nothing else to install, nothing to glue together. That’s the approach this guide sets up.

What you need

A thermal printer. Any of the printers sellers already use for shipping labels work: Rollo, Munbyn, Zebra, Dymo, Brother, Phomemo. Thermal means no ink — labels cost about a cent each. If you already print your Whatnot shipping labels on one, you’re done with this step.

Labels in a size you like. 4×6 (the shipping-label size you already own), or smaller stock like 3×2, 2×1, or 1⅛×3½ address labels if you want compact slips. Eight sizes are supported; matching the setting to the roll in the printer is the whole trick.

The BeamLabel app on the computer you run shows from — Mac (Intel or Apple Silicon) or Windows. Download it here; there’s a 7-day free trial.

The setup, step by step

1. Install and open BeamLabel, and sign in.
2. Sign in to Whatnot inside the app. BeamLabel shows you the real Whatnot site in its window — you run your show from there exactly as you would in a browser.
3. Pick your printer and label size in Settings. The live preview shows exactly what a label will look like on the stock you chose.
4. Choose what’s on the label. Buyer, item title, item number, price, box number, sale type, time — each one toggles individually. Add your shop name to the footer if you like.
5. Print a test label. One button; confirms printer, size, and layout before a live show ever depends on it.
6. Open your show and sell. When an auction closes, the slip prints. That’s the whole workflow.

The one setting worth understanding: print timing

When an auction closes, payment hasn’t always settled yet. You get to choose how to handle that:

• Wait for paid (default): a label prints only after Whatnot confirms payment. Slower by a beat, but every slip that prints represents money received.
• Print when the auction finishes: the label is out before the buyer’s card is even charged — the fastest possible sorting, at the cost of occasionally printing a slip for a sale whose payment later fails.

Either way, always check your orders against Whatnot before you pack or ship — a slip is a sorting aid, not an order confirmation.

What about giveaways and repeat buyers?

The details that separate a setup that demos well from one that survives a 300-sale show:

• Giveaway wins print like any other sale (there’s a toggle if you’d rather they didn’t — some sellers hand prizes over in person).
• The same buyer winning multiple items gets a slip per item, each with a box number, so combined shipping sorts itself.
• A dropped connection shouldn’t end the automation. BeamLabel reconnects on its own and shows an amber dot while it’s trying — no restarting the app mid-show.

Does it work on Mac?

Yes — natively, on Intel and Apple Silicon. Windows 10 and 11 too. Same app, same features, whichever machine runs your shows.

Common questions

Do I need a special printer? No. Whatever thermal printer prints your shipping labels will print your sort slips.

Can I still print a label manually? Always — every sale in the feed has a Print button, and it works regardless of payment status. Reprints after a jam take one click.

What does it cost? 7 days free, then $19.99 your first month, then $29.99/month. One subscription, unlimited labels.
