Odoo Direct Dot-matrix Printing

Implementing Odoo with High-Volume Printing: Mastering Dot Matrix Printer Compatibility

Are you facing challenges printing high volumes of documents – think thousands of invoices daily – with your Odoo system, especially when using dot matrix printers? Many large trading companies rely on dot matrix printers for efficient printing of Purchase Orders (POs), Sales Orders (SOs), Invoices, and Picking Lists, leveraging continuous and carbonized forms to print 3-4 documents at once. However, printing these documents as PDFs can be incredibly slow, potentially taking an entire day!

This is a common pain point with Odoo, as it defaults to PDF printing. While PDFs work well with standard desk jet or laser jet printers, the results are often poor on dot matrix printers. The small dots per inch (DPI) can cause font breakage, leading to unreadable output. While you can increase the DPI, this significantly extends printing times, making it impractical for high-volume scenarios like printing 5,000 invoices daily.

The solution? Implement a proxy printing technique for direct dot matrix printing in Odoo. This involves creating a small web server application on the client's computer, directly connected to the printer. This application listens on a specific HTTP port, ready to receive requests from your Odoo web browser. On the server-side, an Odoo add-on sends the raw print data to this local application via HTTP POST. The raw data is automatically generated based on the document using pre-defined templates.

The outcome? Amazing! You achieve fast, direct printing to your dot matrix printer with perfect results.

This course provides a detailed, step-by-step guide on how to:

• Create the necessary web server application.
• Configure the application for optimal performance.
• Set up the Odoo add-on for seamless integration.
