You can print an issued invoice in a foreign language. In order for the invoice type name to be translated as well, you first need to register the foreign-language variant of the name for the document type.
For details, see our documentation.
Procedure
Open Sales → Document Types → Issued Invoice Types and select the relevant type.
Next to the Name field, click the + icon and enter the name in the desired language.
Save the change.
In the Issued Invoices register, find the document, choose print, and select the English language in the top bar.
ℹ️ Without a registered foreign-language name, the invoice type will be printed in Czech, even if the rest of the report is translated.
