The problem is most probably caused bei the Ghostscript which does the
conversion to the printer's PCL format not being able to cope with the
PDF after the form got flattened. Old cups-filters versions (< 1.22.x)
use pdftocairo or Ghostscript for form-flattening, newer cups-filters
use QPDF and you already observed that with QPDF-based form-flattening
the problem does not occur.
Do the following on your Ubuntu box where you did not yet install the
update.
So what you need to do is to set CUPS logging into debug mode ("cupsctl
--debug-logging"), print another (failing) job, and check bei the log
output of the filters whether flattening happened with pdftocairo or
Ghostscript. pdftocairo is the default. Ghostscript is only used if
pdftocairo fails.
Then you should use the cupsfilter utility of CUPS to run the filter
chain independently. Supply ypur PPD file (from /etc/cups/ppd/ to the
cupsfilter call. And if you choose "application/pdf" as output MIME
type, only the filtering up to pftopdf is done and the output is what
comes out of pdftopdf. Take care, by the logging on the screen, that
here the same utility (pdftocairo or Ghostscript) as in you failed print
jobs is used. Try to display the resulting file with Ghostscript.
in error_log you also find the Ghostscript command line used for the
actual printing (the one you have seen in the PPD but with all command
line arguments inserted). Please run the output also through this
command line.
If you get Ghostscript erroring or producing wrong output, post a
Ghostscript bug with exact Ghostscript command line and the ouput file
of cupsfilter attached, so that the Ghostscript developers can reproduce
it. Post a link to the bug report here.

Title:
Unable to correctly print PDF file: Error: Ignoring spurious ET
operator.
Status in cups-filters package in Ubuntu:
Incomplete
Bug description:
Upstream bug report https://github.com/OpenPrinting/cups-
filters/issues/93.
The university document
[antrag_exmatrikulation.pdf](https://github.com/OpenPrinting/cups-
filters/files/2881078/antrag_exmatrikulation.pdf) causes problems on
different printers.
Printing on the Canon iR-ADV C2225i using the Canon PCL, an error page
is first printed, and on the first page after _Email_ everything is
missing. The second page is fine.
```
**** Error: Ignoring spurious ET operator. Output may be inco ****
```
For that printer a special filter `sicgsfilter` has to be used, and is
distributed by Canon. This also happens with their CQue 4.0-1 release
from September 2018.
```
*FoomaticRIPCommandLine: "gs -q -dBATCH %F -dPARANOIDSAFER -dNOPAUSE %B%A%C
-dPDFFitPage -sOutputFile=- - %D%E | sicgsfilter -MPCL -NP %G%H%I -u&user;
-V"&title;" -n&copies; "
```
On the Epson printer _WorkForce WF-2660_, no error page is printed,
but on the first page everything after _Email_ _is missing_ too.
Trying to use different pdftops renderers did not make any difference.
For example,
```
lpr -o pdftops-renderer=pdftops -P chipprinterpcl antrag_exmatrikulation.pdf
```
gave the same result, the same with `pdftocairo`, `acroread`, `mupdf`.
Following `/usr/share/doc/cups-filters/README.gz` and
https://wiki.ubuntu.com/DebuggingPrintingProblems, I verified that the
exact same PDF is put into the CUPS spool directory, and I captured
the data sent to the printer with the commands below.
$ lpadmin -p chipprinterpclfile -E -v file:/tmp/printout -P
~/chipprinterpcl.ppd
$ lpr -P chipprinterpclfile -o psdebug ~/antrag_exmatrikulation.pdf
I get the attached Postscript file, which indeed contains the error
messages.
