To ensure proper eInvoice printing, follow these steps:
Update to the latest version of UBS from at least version 2024.4.
Customize the format and insert the QR code from einvoice_inv into the icbil format.
Print the invoice from the normal invoice print
Create 2 sets of normal invoice prints, one with a QR code and another without a QR code.
Note: If the QR code is inserted incorrectly, the invoice may fail to print and prompt an error. Ensure the format is properly validated before printing with the QR code.
