PrintLatch 0.1.0

The first public release is a deliberately narrow, local-first PDF print bridge
for Windows 11 x64.

What works

Explicit five-minute pairing for one exact HTTPS browser origin
Rotatable and revocable local-process credentials
Static, unencrypted PDF validation with size and resource limits
Durable local queue with cancel, bounded retry, and restart-safe unknown
state
Authenticated preview and document retrieval
Built-in capture:pdf target for a printer-free end-to-end path
Windows printer discovery and native PDF submission
Dependency-free TypeScript SDK for browser and Node.js Fetch
Per-user PowerShell install and uninstall

Supported: Windows 11 x64, PDF, A4/Letter-style document workflows
Not supported: Windows 10, ARM64, macOS, Linux, raw ESC/POS or ZPL, label and
receipt media, HTML, images, URLs, encrypted PDFs, or remote cloud relay
A succeeded physical-printer job means Windows accepted the submission. It
does not prove that paper emerged.
The executable is not code-signed. Verify SHA256SUMS.txt and the GitHub
build-provenance attestation. Windows may display a SmartScreen warning.

Download the Windows x64 ZIP and SHA256SUMS.txt, verify the checksum, extract
the archive, and run:

Set-ExecutionPolicy -Scope Process Bypass
.\install.ps1

The release archive includes a self-contained capture smoke test:

.\smoke-release.ps1
