Hi,

thank you for all the data! It helps a lot!

From the logs you've provided I see you had problems with running the filter - I see some file not found, permission denied - and lastly execv() is not able to run the filter and ends with error:

D [15/Sep/2023:16:36:54 +0800] [Job 14] execv failed: Exec format error

The source of this error is that the driver you've installed is for MacOS, not Linux.

I searched a little and found this page where they mention some ways what to try to fix it, but I haven't tried any myself. Or ask the manufacturer for Linux driver.

Or you can try whether the printer can work without driver (it is a model from 2012, it could) - how-to
