The OER Product Label Pro module extends the label generation package with a customizable WYSIWYG style builder, custom dimension grids, and relational field mappings. It empowers administrators to design custom, professional label templates containing dynamic barcode symbologies, promotional prices, logos, and custom notes, all without writing a single line of QWeb XML code.

To install the Pro module:

1. Ensure the base product_label_oer module is active.
2. Place the oer_product_label_pro addon folder inside your Odoo custom addons directory.
3. Navigate to Apps, click Update Apps List, and search for OER Product Label Pro.
4. Click Activate.

Company Settings

Go to Settings ‣ Inventory / Products:

• Preview Product Type: Choose between a static Demo Product and the active Real Product during design previewing.
• Demo Pricelists: Configure price maps used during designer rendering previews.

User Options

Go to Settings ‣ Users ‣ OER Labels:

• Default Template: Set the default design layout for the current user.
• Allowed Templates: Restrict users to specific styles. Leave empty to allow all.
• Immediate Printing: Enable printing directly to the browser view.

• Relational Fields L1/L2: Bind sections to related columns (e.g. product_variant_id.product_tmpl_id.categ_id.name).
• Visual Highlights & Grid Sizing: Build labels using accurate dimensions, margins, paddings, rows, columns, and gaps.
• Barcodes & QR Codes: Generate EAN8, EAN13, Code128, DataMatrix, or QR codes with automatic absolute path redirects.
• Live visual HTML Preview: Dynamic rendering panel shows layout modifications instantly.

1. Go to Settings ‣ Technical ‣ Reporting ‣ Label Templates.
2. Click New Template to launch the template configuration wizard.
3. Fill out sheet sizes, grid columns, rows, margins, and gaps. Click Create Design Template.
4. Add Design Sections. Select types (Text, Model Field, Price, QR, etc.) and configure fonts, alignment, border width, and text colors.
5. Enable Live Preview at the top to check spacing as you design.

The template configurations compile to clean HTML styles at print time. The module registers an abstract report class:

report.product_label_oer.qweb_custom_design_placeholder

This abstract model serves as a bridge, mapping layout parameters (e.g. cols, rows, label_style, skip_places) from the print actions to the QWeb rendering context.

Only system administrators (group base.group_system) have access to define and modify templates or template sections. Normal employees are restricted to choosing allowed templates during print jobs.
