We are currently trialing PDFCreator Server.
I raised a support case via the Web Form and got a reply back from support@pdfforge.org back on 30/04 and subsequently provided screenshots and debug logs.
I've chased a couple of times now since, and have still not got a reply from support. It appears I'm simply being ignored.
If the issue can be resolved and we can prove our POC, we will likely purchase the product, but as Support appears to be non existent we will likely be looking for an alernative product following the weekend.
Not good.
