It is possible to have a different PDF template for each interface language. For example: a PDF template with the logo and tagline of the company in French (fr-FR), and another in English (en-US).
In the Print templates administration interface, upload one template for each interface language, as shown in the following example:
template.$LANGUAGE_ISO_CODE.vm
template.fr-FR.vm
template.en-US.vm
If no corresponding interface language is available, the language of the PDF template reverts to the default one: pdf-template.vm.
