Whatnot labels printing sideways, too small, or not at all

This is the most common one, and it is almost always a mismatch between the label file and the printer's page setup. Whatnot hands you a label sized for 4x6 inches in portrait. If the printer driver is set to letter, or to landscape, or to a 4x6 profile that expects landscape, the print system rotates the artwork to fit the page it thinks it is using.

Fix it in the printer driver, not in the PDF viewer. Set the paper size to 4x6 inches exactly, set orientation to portrait, and set scaling to none or 100 percent. Then open the label and print without touching the viewer's own rotate or fit controls, because those stack on top of the driver setting and you end up fighting two rotations at once.

If you print from a browser, check the browser's own print dialog too. Chrome keeps a per-printer memory of paper size and margins, and it will quietly reapply letter to a job you meant for a label roll.

Too small nearly always means a 4x6 label was sent to an 8.5x11 sheet with fit-to-page turned on. The label keeps its aspect ratio, shrinks to fit the paper, and lands as a small rectangle in one corner. Too big is the same setting in reverse: a label scaled up to fill a page it was never meant for.

The setting to find is called scale, fit to page, or shrink oversized pages depending on the software. Turn it off. Set scale to 100 percent and the paper size to match the label you physically loaded. If you genuinely are printing onto letter sheets with adhesive halves, choose the letter label format Whatnot offers rather than scaling the 4x6 one, because a scaled barcode is the thing that gets packages returned.

Test one label before a batch. A scaling mistake found on label one costs a label. Found on label two hundred, it costs the evening.

Work through this in order, because the cheap checks catch most cases. Confirm the printer is the default and is not paused or offline. Confirm the roll is loaded the right way round, since direct thermal only marks one side and a reversed roll prints a blank label perfectly happily. Then print the printer's own self test to prove the hardware is fine before blaming the file.

If the hardware tests clean and the job still dies, the usual culprit is the print spooler holding a stuck job. Clear the queue, then send a single label. On a thermal printer, also check the driver's darkness or density setting: too low and the label physically prints but comes out too faint to scan, which reads as a printing failure at the carrier counter rather than at your desk.

One detail worth knowing: thermal printers do not print gray. Anything in the artwork that is not pure black can come out faint or missing entirely, so stick to the standard label format rather than anything re-saved through an image editor.

This one is not a printing problem at all, and treating it as one wastes an hour. If there is no label to print, the order has not reached the state that produces one. The usual reasons: the show has not finished settling, the order is still waiting to be combined with the same buyer's other wins, the buyer's address failed validation, or the item has no weight class set, so there is nothing to buy postage against.

Check the order itself before touching the printer. If the order shows as awaiting shipment but has no label, look at the weight class first, because a missing or wrong weight is the most common blocker and the one you can fix yourself immediately. If the address is the problem, the buyer has to correct it, and no amount of retrying will generate the label until they do.

You can view and share labels from the phone app, but phones do not drive label printers well. Bulk label generation and the print controls that matter live on the web dashboard at whatnot.com, not in the mobile app, so anything involving more than one or two packages belongs on a computer.

If you are away from your desk, the practical move is to hand the label off rather than fight it: send the label to yourself and print it later, or use your printer manufacturer's own mobile app, which owns the paper size and orientation settings that the generic phone print path does not expose. Expect to reset the size and scaling the first time.

Printing orders one at a time after a busy show is the slowest possible path. From the web dashboard, open your shipments, select the show's orders, and generate the labels as a batch, then print the whole file in one job. Sort the printed stack in the same order you staged the sold items and pack-out gets much faster.

Two things to confirm before you send a batch. First, that combined orders have finished combining, so one buyer does not get three separate labels for one box. Second, that cancellations from the show are excluded. Both are easy to miss late at night, and both are expensive to unpick afterwards.

Sellers who never think about label problems tend to have the same setup: a thermal printer that takes 4x6 direct thermal labels, one saved printer profile with scaling off and orientation locked to portrait, and a habit of printing one test label before any batch. That combination removes sideways, too small, too big, and faint in one go.

The remaining problems are workflow rather than hardware, and that is the part we build. LiveStreamPro's printing system prints without a print dialog at all, so there is no per-job paper size to get wrong: label templates pin the size and orientation once, automatic printing sends the wave when the show ends, print stations let more than one person pack at once, and print reconciliation tells you which labels actually came out so nothing ships twice or not at all.

If you want the broader picture first, the guide to printing Whatnot shipping labels covers the manual and automatic flows end to end.
