--- Comment #10 from Johannes Meixner ---
Petr Gajdos,
FYI what I did on my Leap 42.1 system to find out that
it is poppler that produced the problematic PostScript:
Store attachment#661731 as /tmp/TA3060.ppd
and then set up a testing queue that prints into a file.
To print into a file have in /etc/cups/cups-files.conf
FileDevice Yes
and for meaningful CUPS logging have in /etc/cups/cupsd.conf
LogLevel debug
and restart the cupsd.
Then do
# lpadmin -p bug961864 -v file:/tmp/bug961864.prn -P /tmp/TA3060.ppd -E
and
# date | lp -d bug961864
and inspect the printing output in /tmp/bug961864.prn that contains

The output of "date" is 'text' that is converted to PDF via texttopdf
and further converted pdftopdf.
That PDF is converted into PostScript via /usr/lib/cups/filter/pdftopdf
that is only a wrapper that calls the system pdftops
which is /usr/bin/pdftops from poppler-tools.
