Welcome... Unfortunately, I can't find what is wrong by looking there. There is a section where it appears to send the print job:
Look at line 129, it seems to be the start of a print job. On line 142 it is applying the filters. ps to pdf, pdf to pdf, then pdf to raster, then raster to printer. On line 147 it says "job-sheets=none,none". Line 154 says that the job is cached as "/var/spool/cups/d00010-001" - you can check if the file is still there, it probably is a pdf inside (run "file /var/spool/cups/d00010-001" to find out).
Line 186 seems to start each filter job.
I do not know what is the result of each filter. Did they succeed? Can we look at temporary files?
At line 190 it starts the backend to send it via USB to the printer itself, I suppose.
Maybe at line 193 it says it finished sending the print job.
Line 287 is a ghostscript command used. What for...?
And here I get lost, because on line 451 I see the same thing, so I don't know if you repeated the print request or what happened.
We need to know for sure that the log is for a single print job, and where does the log start. I'm not trained in reading CUPS logs...
It seems the previous print job, although it "printed" a blank page, was still in the queue, oddly enough. I will rerun the test cleanly without any print jobs and submit a new log file.
I see a bunch of cupsdWriteClient commands. I see a "data_remaining=994" with the number diminishing each time, but barely so.
Line 590 seems to be sending print job and displaying the percent.
