# pos_closing_receipt
Odoo 19 custom module — automatically prints a **session closing summary** via the browser print dialog when a POS session is closed.
---
## Features
- Intercepts the POS session closing flow.
- Reads the real session name from the server (the sequence assigned at session opening, e.g. `Mie Mapan Barata00001`).
- Collects payment totals per payment method (cash + all non-cash methods).
- Triggers the browser's native print dialog (`window.print()`) — no IoT Box or network printer required.
- Prints cleanly to thermal receipt printers (≤ 80mm paper) via the browser.
- Fault-tolerant: print failures are caught and logged; they never block the session closing process.

## Installation
1. Copy the `pos_closing_receipt` folder to your `customaddons/` directory.
2. Add the path to `addons_path` in `odoo.conf` if not already included.
3. Restart the Odoo server.
4. Activate **Developer Mode** in Odoo settings.
5. Go to **Apps** → search for `pos_closing_receipt`**Install**.
Or install via CLI:
```bash
python odoo-bin -u pos_closing_receipt --config=odoo.conf -d <your_database> --stop-after-init
```

## How It Works
### Sequence Timing
In Odoo, `pos.session.name` starts as `"/"` (the default) and gets the real sequence (e.g. `Mie Mapan Barata00001`) only when the session is **opened** via `set_opening_control()`. The frontend JS never receives this updated value, so we perform one server-side read before closing:
```js
const result = await this.pos.data.read("pos.session", [this.pos.session.id], ["name"]);
realSessionName = result[0].name; // → "Mie Mapan Barata00001"
```
### Print Flow
```
User clicks "Close" in POS closing popup
├─ 1. Fetch real session name from server (pos.data.read)
├─ 2. Collect payment data from props (default_cash_details, non_cash_payment_methods)
├─ 3. Call super.closeSession() — standard Odoo closing
└─ 4. Session state === "closed"?
└─ Yes → printer.print(ClosingReceipt, data, { webPrintFallback: true })
└─ Browser print dialog opens
```
### Web Print (No IoT Box)
Uses Odoo's built-in `printer` service with `webPrintFallback: true` — the same mechanism used by the standard POS order receipt:
- If an IoT Box printer is configured → sends to the hardware printer.
- If **no** printer is configured → falls back to `window.print()` (browser dialog).

## Customization
### Change the receipt layout
Edit `static/src/app/closing_receipt.xml`. The template uses standard HTML table layout with inline CSS for maximum printer compatibility.
### Add a company logo or header
Add a `<div>` above the session name section in the XML template. Use base64-encoded images if needed.
### Change paper width
The default `max-width` is `320px` (80mm thermal). For 58mm paper, reduce to `220px`:
```xml
<div class="pos-receipt" style="... max-width: 220px; ...">
```

## Changelog
### v1.0.0

- Web print via `window.print()` (no IoT Box required).
- Reads real session sequence name from server at print time.
- Fault-tolerant: print errors never block session closing.
