Getting a PDF out of the Headless Client

Classic Servoy
1

We are unable to generate a PDF using the pdf_output plugin via Servoy
Headless Client because of the following exception:

Cannot print document

We’re using Servoy version 2.2.7 and pdf_output plugin.

Any help would be appreciated. Thanks.

Seems I get bitten by the same issue.
Is it even possible to create a PDF using a batchprocessor (headless client)?

What error (stack) do you receive ?

You can open a case about this, not sure from the stack what goes wrong.
