User interface localization of regular IPP attributes and Internal IPP Extensions are part of SavaPage.
Localization of External IPP
Extensions text, and optionally 16x16 pixel icons, must be supplied by
XML files in the /opt/savapage/server/custom/cups/i18n
directory. The default ipp-i18n.xml file is reserved for the
English locale. Variants are created by appending the language locale to the base
file name. For example: ipp-i18n_de.xml is the German
version.
An annotated ipp-i18n.xml.template file is available in the
target directory.
See Section 3.5.2.3, “Custom Text and Icons” for an example screenshot.
ipp-i18n*.xml files can also be used to override IPP
localization that is part of SavaPage.
After creating or updating any of the ipp-i18n*.xml
files you might need to restart the server to see the effect.
