Browser Print agent for macOS

A small menu-bar app that lets any web app print to a Zebra label printer on your Mac — over USB, your network, or Bluetooth. Wire-compatible with Zebra's official Browser Print, so the same web tools that work on the Zebra Mac/Windows agents work here unchanged.

What this is for

Browsers can't talk to USB or Bluetooth devices directly. This app runs a tiny local service that bridges the gap: web apps send raw ZPL to https://localhost:9101/write, and the app forwards it to your connected Zebra printer.

Comes with a full Settings app — diagnostics, label calibration, quality presets (Speed / Default / Quality / Barcodes), per-printer offset tuning, and a per-site approval flow that matches Zebra's official agents. Adds network + Bluetooth printer support the stock agent doesn't have.

Download

macOS (Apple Silicon + Intel)

Universal .pkg — double-click to install both apps + auto-start

pppro-browser-macos_*_darwin_universal.pkg

Download

Installing the .pkg (recommended)

Double-click pppro-browser-macos_…_darwin_universal.pkg in your Downloads folder.
macOS will show "…cannot be opened because Apple cannot check it for malicious software". Click OK to dismiss.
Open System Settings → Privacy & Security. Near the bottom you'll see a line about the .pkg being blocked — click "Open Anyway".
Re-double-click the .pkg. macOS will now show an Open button — click it, and the standard macOS installer opens.
Click through (Continue → Agree → Install). Enter your password when prompted. The installer copies both apps to /Applications, configures auto-start, and launches the agent — the printer icon appears in your menu bar within a few seconds.
Click the menu bar icon → Settings… to add your printers and run a test print.

The Open Anyway step is a one-time bypass while Apple Developer ID notarisation is being set up. Once notarised it goes away — installs become a straight double-click.

Fleet deployments (Munki / Jamf / Ansible)

For scripted rollouts, grab the .zip instead — same contents, but with Install.sh / Uninstall.sh for non-interactive deploys.

pppro-browser-macos_latest_darwin_universal.zip ↓

Unzip — you'll get a folder with both .app bundles and the install scripts.
Run ./Install.sh — copies both apps to /Applications, installs the LaunchAgent, and bootstraps it for the current session.

If macOS reports a downloaded app as "damaged", strip the quarantine flag:

xattr -dr com.apple.quarantine "/Applications/Print Platform Pro Browser.app"
xattr -dr com.apple.quarantine "/Applications/PrintPlatformProBrowserAgentUI.app"

Currently ad-hoc signed while Apple Developer ID notarisation is being set up. macOS will ask for one Privacy & Security bypass on first install; once notarised the prompt goes away.
