Thank you for getting back.
So far I’m not seeing anything obvious to my novice eyes. The first 3 filters work fine. I cannot determine the state of the last.
I did come across this (which it seems you were helping on) describing an issue with a slightly different model using the same driver:
I decided to find a large multi-page PDF and attempt to print it. The result: it tried to print it.
Out of the 100+ pages in the PDF, the printer log reports: ‘18 (received)’, which it attempted to physically print. I also noticed that the first page physically printed actually started at page #5 of the PDF file.
I have not looked through it yet, but this is the error_log for the ‘at least it printed something this time’ print job: https://pastebin.com/JxG0K4rp
