How to Print Labels From a Mac
macOS sees your label printer through CUPS, but getting an app to print to it at the right size is fiddly: Preview loves to scale, and many label printers (MUNBYN especially) ship Windows-only software with no real Mac option. Here's the simple way to print labels on a Mac.
Printing steps
- Connect your label printer; macOS installs it via CUPS. Check it appears in System Settings → Printers & Scanners.
- Install the free PaperReady Print Bridge for macOS, a universal build that runs natively on Apple Silicon and Intel.
- Open the PaperReady app; every printer macOS knows about appears, label printers highlighted first.
- Compose your label and choose the size (4×6, address, or barcode).
- Print directly to the label printer: no Preview, no scaling surprises.
Choose matching paper dimensions and print at 100% / Actual size. Individual label PDFs and five-label batch proofs work without an account. Complete batches require Pro. Direct printing depends on your printer driver and current platform support. PaperReady does not purchase postage.
Frequently asked
My label printer's software has no Mac version. Can I still print?
Yes. As long as macOS installed the printer (most do automatically via CUPS), PaperReady prints to it, which is exactly why Mac users with MUNBYN and similar printers rely on it.
Why does Preview shrink my label when I print?
Preview scales the file to the page. PaperReady sends the job to the label printer at true size, so a 4×6 stays 4×6.
Does the Mac agent run on Apple Silicon?
Yes, it's a universal binary, so it runs natively on both Apple Silicon (M-series) and Intel Macs.
