To print internal transfer receipts using a thermal printer in Odoo 17, you'll need to configure a custom report format suitable for thermal printing and ensure it is connected to the stock transfer process. Here's a step-by-step guide:

1. Understand the Requirements

• Internal Transfer Receipts: Refers to printing a formatted document that details the products being transferred between warehouses.
• Thermal Printer: Requires compact, printer-friendly formatting for smaller receipt sizes.

2. Create a Custom QWeb Report for Internal Transfers

Odoo uses QWeb for rendering reports. You’ll need to define a new QWeb report that is tailored for thermal printers.

Steps to Create the Report:

1. Create a Custom Module If you don’t already have a custom module, create one with the following structure:

   custom_internal_transfer_report/
   ├── __init__.py
   ├── __manifest__.py
   ├── reports/
   │   ├── internal_transfer_report.xml
   │   └── report_templates.xml
   

2. Update __manifest__.py Define your module and ensure it depends on the stock module:

   {
       'name': 'Internal Transfer Thermal Report',
       'version': '1.0',
       'depends': ['stock'],
       'data': [
           'reports/internal_transfer_report.xml',
           'reports/report_templates.xml',
       ],
       'installable': True,
   }
   

3. Define the Report in internal_transfer_report.xml Link the report to the internal transfer model (stock.picking):

   <odoo>
       <report
           id="action_report_internal_transfer"
           model="stock.picking"
           string="Internal Transfer Receipt"
           report_type="qweb-pdf"
           file="custom_internal_transfer_report.report_internal_transfer"
           name="custom_internal_transfer_report.report_internal_transfer"
           print_report_name="'Internal Transfer - %s' % (object.name)"
       />
   </odoo>
   

4. Create the Report Template in report_templates.xml Design a compact layout for the thermal printer:

   <odoo>
       <template id="report_internal_transfer">
           <t t-call="web.basic_layout">
               <div class="page">
                   <div class="text-center">
                       <h3>Internal Transfer</h3>
                       <p><strong>Reference:</strong> <t t-esc="doc.name"/></p>
                       <p><strong>Date:</strong> <t t-esc="doc.scheduled_date"/></p>
                   </div>
                   <table class="table table-condensed">
                       <thead>
                           <tr>
                               <th>Product</th>
                               <th>Quantity</th>
                               <th>Unit</th>
                           </tr>
                       </thead>
                       <tbody>
                           <t t-foreach="doc.move_ids_without_package" t-as="line">
                               <tr>
                                   <td><t t-esc="line.product_id.display_name"/></td>
                                   <td><t t-esc="line.product_uom_qty"/></td>
                                   <td><t t-esc="line.product_uom.name"/></td>
                               </tr>
                           </t>
                       </tbody>
                   </table>
               </div>
           </t>
       </template>
   </odoo>
   

5. Connect the Report to Internal Transfers
   • Go to Inventory > Configuration > Document Layouts.
   • Assign your custom report as the default report for internal transfers.

3. Adjust the Report for Thermal Printing

Thermal printers typically require smaller paper sizes and specific styles.

• Set Page Size: In your template, add a style block:

  <style>
      @media print {
          @page {
              size: 80mm auto; /* Adjust for your thermal printer */
              margin: 5mm;
          }
          body {
              font-size: 10px;
          }
          table {
              width: 100%;
              border-collapse: collapse;
          }
          th, td {
              border: 1px solid black;
              padding: 5px;
          }
      }
  </style>
  

• Test the Output: Print the receipt to your thermal printer and tweak the layout as needed.

4. Add a Button for Printing

To make printing easier for users, add a button in the Internal Transfer form view.

Modify the internal_transfer_report.xml:

<record id="stock_picking_internal_form_view" model="ir.ui.view">
   <field name="name">stock.picking.internal.form</field>
   <field name="model">stock.picking</field>
   <field name="inherit_id" ref="stock.view_picking_form"/>
   <field name="arch" type="xml">
       <xpath expr="//header" position="inside">
           <button name="%(action_report_internal_transfer)d" string="Print Receipt"
                   type="action" class="btn-primary" />
       </xpath>
   </field>
</record>

5. Install and Test

1. Restart your Odoo server and install your custom module.
2. Create an internal transfer and validate it.
3. Use the Print Receipt button to generate and print the thermal receipt.

6. Advanced Features (Optional)

• Auto-Print After Validation: If you want the receipt to print automatically after validation, add this functionality to the button_validate method in stock.picking.
• QR/Barcode for Tracking: Add a QR or barcode to the receipt for easier tracking. Use the barcode widget in your QWeb template:

  <img t-att-src="'/report/barcode/?type=QR&value=%s' % doc.name"/>
