Printers using Zetaprints web-to-print system can now customise their homepage greeting and and link to their own presentation.
This feature is useful for printers using password protected catalogues only. Their customers land on a login page first. The greeting message can help them understand where they are and what to do next. E.g. that they need to register, who can login, who provides the services, etc.
Detailed instructions can be found in this help post.
