I'm a developer working on a web based SaaS application that my clients use to generate reports to send to their own customers - my clients get paid to produce these reports.
I have a client that requires the use of the Arial font in their reports in accordance with their style guide.
I know that I can display Arial in browser-based text editors without including the font-face by referencing the font already on the user's PC, so I don't think I have any licensing issues there. However, I'm unsure of the licensing requirements around generating a PDF for them that they will then send to their clients.
They pay us per user per month to use our software, not per report, and report generation is only one small part of the value we provide to them. However, the report generation is done on our server (Linux/Ubuntu), so we'd need to install the fonts there for our customers to be able to use them.
We do not redistrubute the font files themselves, only documents made using the font.
I'm having issues deciphering when a license is required for me to use a font and when it isn't, and I can't find any results that relate to my specific circumstance.
Do I need to purchase a server license to use Arial to generate their reports?
