How to Print Labels From a PDF at 4x6 True Size
The label arrives as a PDF from the carrier or marketplace, and the browser wants to scale it down onto a letter page. You want it on the thermal printer at full 4x6, edge to edge.
- Open the PDF and note the label size. Most shipping labels are 4x6 inches, though some carriers park that 4x6 in one corner of a letter-size page.
- Ignore the browser print dialog. Its Fit and Shrink to fit options are exactly what turn a sharp 4x6 into a small label stranded in white space.
- Install the free Print Bridge from /download/. It runs on Windows, macOS, and Linux and auto-detects the label printers your computer already sees, USB or network, any brand.
- Open /app/, drop in the PDF, and choose your 4x6 thermal printer. The app reads the label's real dimensions and sends it at true size, so it prints edge to edge instead of scaled to a page.
- Print. The file stays on your machine, comes out at full 4x6, and costs nothing per label with no brand lock-in.
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 PDF label print small or off-center?
The browser or PDF viewer is scaling the page to fit letter paper, which drops a 4x6 label into the corner of an 8.5x11 sheet. Print Bridge sends the label at its real dimensions instead, so it fills the 4x6 stock.
The label is 4x6 but the PDF page is letter size. Will it still print right?
Yes. Carriers often embed a 4x6 label inside a larger letter-size PDF. The app reads the label's own dimensions, not the page size, so you get a full 4x6 either way.
Do I need a specific brand of thermal printer to print the PDF?
No. Print Bridge prints to any printer your operating system already has installed, including Zebra, DYMO, Rollo, Brother, and MUNBYN. If the OS can see it, the app can send your PDF to it at true size.
