That product's license tiers are a complete non-starter, unprofessional, and they "call for pricing" on the only potentially usable license (but don't provide a copy of the CSO License for review before calling).
> A Prince Server License can be installed on a single server to produce PDF documents for company-internal use, or documents that are made available to everyone free of charge.
They never define what "company-internal use" means, even in the actual terms[0]. This was clearly written by a non-lawyer, and any company worth its salt wouldn't touch this (the "FAQ" isn't a legally binding document, and even that is incredibly vague/unhelpful).
> You many not use Prince to generate documents that are part of a Commerial Service, for example invoices and monthly statements.
So "company-internal use" doesn't include order/remittance/invoice/receipt to your company's suppliers/vendors? That's just bizarre, the whole licensing is. The "Service License" feels like a Honey Trap.
Having used it for over a decade, it's a wonderful tool.
