Watchfolder Printer — Automatic Photo Booth Printing Software for Windows

Set the watch folder. Add photos with software/dropbox/drive/photo booth software etc. They print automatically. It’s that simple.

Watchfolder Printer is a lightweight Windows desktop app designed for photographers, event companies, and photo booth operators who need hands-free printing. Point it at any folder — local or cloud-synced — and every new image that lands there prints automatically.

The optional AI-powered face detection counts unique faces in each photo and prints the right number of copies — no manual counting needed at busy events.

Run multiple instances with separate profiles to drive different printers from different folders simultaneously. Each profile saves its own printer, margins, paper settings, and detection preferences independently.

No internet required. No subscription. No cloud. Just fast, reliable, automatic printing.

Features:

• Auto-Print from Any Folder — Monitor a local or cloud-synced folder (Dropbox, Google Drive, OneDrive). New images print instantly without touching a button.

• AI Face Detection — Automatically counts unique faces in each photo and prints one copy per person. Perfect for events, photo booths, and group shots.

• Smart Image Fitting — Choose between Scale to Fit, Stretch to Fill, or Use Exact Image Size. Auto-rotates photos to match your paper orientation.

• Multi-Printer Support — Run multiple instances with different profiles — one folder per printer, each with its own settings. Great for multi-station setups.

• Browse & Reprint — Visual thumbnail grid of your watch folder. Select any image and reprint with custom copy count — no file manager needed. No separate iPad sharing stations just for printing.

• Full Printer Control — Access native printer properties, set custom margins, and save settings per profile. Your paper size, cut mode, and quality settings persist.

• System Tray Operation — Runs quietly in the background. Start/stop watching from the tray menu. Launch additional instances on the fly for multi-printer support from same device.

• Licensed for Multi-Device— Install on up to 4 devices per company. No subscription, no cloud dependency, no recurring fees. Always ready, even if your internet goes down.
