Thank you very much for taking your time to help investigate this
issue and providing us a method to continue the investigation even when
you are so busy.

A problem I have observed in the logs is that foomatic-rip calls
Ghostscript twice here. Once to convert the PDF input into PostrScript
and then to convert the PostScript into PCL XL.
Can you please try to set up your printer with the attached PPD file?
TRhe difference to the original is the foll
One thing you should test is to run Ghostscript separately. For this,
take the Ghostscript command line from the error_log and feed your PDF
file directly into it. How long does it take? Is it much faster than
running as part of the print job? Or is it more or less the same?

and providing us a way to judge if "Ghostscript" causes the slowdown of
"pdftops" even when you are so busy.

Dear Till,
Thanks for your investigation of this problem.
Below are the information we found maybe helpful for the investigation:
As we said before:"The phenomenon that print jobs slower in 16.04 is more
obvious when printing many jobs in the same time."

I have looked into the error_log files and the processing by the filters
on 16.04 takes ~20 seconds and on 14.04 less time. The 326 seconds you
observe on 16.04 is caused by the printer's processing of the PostScript
it receives. The PostScript is generated by Ghostscript (you find the
