Print a USPS Shipping Label at True 4x6 Size

You paid for postage in Click-N-Ship and got a 4x6 label back. Now it has to land on thermal stock at exactly 4x6, edge to edge, with the barcode full size instead of shrunk into the corner of a letter sheet.

  1. In Click-N-Ship, pick the 4x6 label format if USPS offers it for your service. If it only gives you the standard PDF, that's fine too. PaperReady sets the size at print time either way.
  2. Save the label PDF. Skip the browser's Print dialog and any "fit to page" checkbox. That setting is what squeezes a 4x6 label onto letter paper and drops the barcode below scannable size.
  3. Install the free Print Bridge (/download/) on Windows, macOS, or Linux. It finds the 4x6 thermal printer already connected over USB or network. Zebra, Rollo, MUNBYN, Brother, DYMO. Whatever the OS can see.
  4. Open the web app (/app/), drop in the USPS PDF, pick your thermal printer, and print. It goes out at true 4x6, edge to edge, with no dialog in the way. The tracking barcode stays sharp enough to scan on the first pass.
  5. Shipping a stack? Load the day's labels and send them to the printer in one run. Prints are unlimited and there's no per-label fee.
PaperReady prints straight to your label printer at true size, with no PDF-export-then-reprint step, unlimited labels, and no per-label fees, on Zebra, DYMO, Rollo, Brother and MUNBYN across Windows, Mac and Linux.

Frequently asked

Why does my Click-N-Ship label print tiny with a wide white border?
A browser or PDF reader is scaling the 4x6 label down to fit letter paper. Print Bridge ignores fit-to-page and sends the label to your thermal printer at its real 4x6 dimensions, so it fills the stock edge to edge and the barcode scans.
Can I use my existing Rollo or MUNBYN instead of a specific brand?
Yes. PaperReady is brand-agnostic. If the OS can see the printer over USB or network, Print Bridge can send to it. Zebra, Rollo, MUNBYN, Brother, DYMO, or any other 4x6 thermal unit. No brand lock-in, no per-label metering.
Is there a per-label charge on top of the postage I already paid USPS?
No. PaperReady never meters prints and never blocks a print. Free covers one workstation with unlimited USPS labels and 7-day history. Pro ($12/mo) adds batch printing, three workstations, and full history.
