BLUETOOTH PREVIEW: Windows hardware verification is pending.

DianDot Print Bridge 1.3.4 - Windows 10/11 - UNSIGNED

1. Extract the ZIP (do not run from inside the archive).
2. Close DianDot on the print host while no tickets are printing.
3. Double-click Install-DianDot-Print-Bridge.cmd, type INSTALL, then wait for SUCCESS.
4. Open DianDot > Management centre > Kitchen & printers.
5. Choose Windows USB automatic and Find Windows printers.
6. Select Xprinter XP-80 (or your exact installed ESC/POS receipt printer).
7. Save printer rules. Use Connection test and check paper, including Chinese.
8. Expand Shared printing and Use this device as print host.

Keep this Windows PC powered on, awake, signed in, with DianDot visible.
Handhelds signed in to the same restaurant send jobs through this host.
The helper starts at Windows sign-in. DianDot must also remain open.
A submitted job means Windows accepted the data, not confirmed physical paper.
If delivery is uncertain, check paper before retrying to avoid duplicates.

USB supports local physical printer queues on USB/DOT4/LPT/COM ports.
Install the manufacturer's driver first. Virtual PDF/file printers are excluded.
With helper 1.3.4, DianDot renders USB tickets into 576-dot monochrome images.
Future font, spacing and layout changes arrive with DianDot; reload the host page.
Only transport changes or helper bug/security fixes require another helper update.
Existing cloud jobs stay compact; raster images are generated on the print host.
Older helpers continue using their existing layout until upgraded.
Older DianDot pages continue to work with 1.3.4 via the legacy renderer.
This avoids printer code-page and Chinese ROM/font dependencies.
Microsoft YaHei or SimSun must be installed (normally present on Chinese Windows).
Network ESC/POS printers remain supported on port 9100.
USB / browser is still the manual browser print option.

Uninstall: Uninstall-DianDot-Print-Bridge.cmd.

If installation fails, the window stays open with startup errors. Send a screenshot.

Installer changes:
- Uses a separate immutable versions/1.3.4 directory; does not overwrite live code.
- Verifies copied file hashes before stopping the old helper.
- Updates sign-in startup only after the new helper passes a health check.
- Attempts to restart the previous helper if startup fails; preserves old files.
- Logs to %LOCALAPPDATA%\DianDot\PrintBridge\install.log.
- Reinstalling an identical, running version does not restart it.

This remains a CMD/PowerShell installer, not a signed EXE/MSI.
No firewall rules, antivirus exclusions or machine-wide policy changes are added.
360/Windows security warnings may still occur. Do not disable protection.
If blocked, stop and send the alert and install.log to support.
File hash checks detect copy errors; they are NOT publisher authentication.
The helper listens only on 127.0.0.1, never on the public/LAN interface.

BLUETOOTH RECEIPT PRINTERS (Windows):
1. Pair the Sunmi printer in Windows Bluetooth settings once.
2. In DianDot select Bluetooth printer (Windows), then Search Bluetooth.
3. Select the paired printer by name. No COM port input or commands required.
4. Use Connection test, check actual paper, then save the printer rules.
5. Use this PC as the shared print host. Keep DianDot visible and the PC awake.

Only associated outgoing RFCOMM serial ports are offered; incoming ports are excluded.
If no printer appears, check Windows pairing and printer power.
After a partial write or timeout, check paper before any manual retry.

Supports paired Bluetooth serial (SPP/RFCOMM) ESC/POS receipt printers, regardless of brand.
BLE-only and proprietary printers are not supported. Verify a physical test receipt before service.
Discovery lists paired serial devices; select your receipt printer, not another Bluetooth device.
