Hi,

If you’d like to print your Sales Orders in a ticket (receipt-like) format using Odoo 10, you can do it with built-in tools:

    Enable Developer Mode.

    Create a new paper format (e.g., 80 mm wide) under Settings → Technical → Reporting → Paper Formats.

    Duplicate the Sales Order report and assign it your custom format.

    Edit the QWeb template to simplify layout—compact lines, reduced margins.

This gives you full control over formatting without extra modules.

Hope it helps
