So it is a PDF and not Postscript?
By all means do add information, but also please explicitly answer the questions i ask. It’s so much easier that way,
Of course you can get the printer debug info (not terminal output!) regardless of print job success/failure. Please read the instructions again.
If it is indeed a PDF (please just be clear about this); the questions from my first post still apply - i.e. does the document work in Documents/pdftocairo, and what transfer formats can you choose in the app?
