<div class="moz-cite-prefix">Hi all!<br>
<br>
I skimmed through this thread and the bug report itself, but I'm
not really sure what is the state of the investigation, but I made
some tests today morning, and here my results (forget it, if You
already come to the same conclusion):<br>
<br>
1. All ps files pointed to by the thread and the bug report and
all I produced by my own with pdftops -level3 can be rendered with
gs 9.0.6 without any problems!!!<br>
2. The postscript output of Form DS-7002.pdf
(<a class="moz-txt-link-freetext" href="https://bugs.freedesktop.org/attachment.cgi?id=89534">https://bugs.freedesktop.org/attachment.cgi?id=89534</a>), produced
with pdftops -level3, can be opened with Adobe Acrobat X under
Windows!!!<br>
3. But the same ps file can't be rendered with Adobe Distill X
under Windows, then I get the same error log as in
<a class="moz-txt-link-freetext" href="https://bugs.freedesktop.org/show_bug.cgi?id=69485#c2">https://bugs.freedesktop.org/show_bug.cgi?id=69485#c2</a> !!!<br>
4. All other ps files can neither be opened with Adobe Acrobat X
nor be rendered by Adobe Distill X<br>
<br>
My conclusion, especially because of 2. and 3.: It is a bug in the
Adobe PS engine!<br>
<br>
Cheers,<br>
Thomas<br>

<div>Ross,</div>
<div>That is amazing, thanks again. </div>
<div>While we're on this subject, maybe you could have a
look at the PS output produced by pdftops, when processing
the same file? </div>
<div>The resulting level 3 PostScript cannot be parsed by
Distiller either, the error is </div>

<div>The PS file can be retrieved from here, it is 18Mb in
size. (Unlike pdftocairo, pdftops generates huge PS files.
This particular one gets 10x larger when I provide
licensed fonts to pdftops.) </div>

<div>Thanks Adrian,</div>
<div>I will certainly file a bug to cairo postscript
component. We're on poppler mailing list here, prhaps you
could provide any advice to poppler team on how to invoke
that part of code that currently is not getting
activated? </div>

<div>Unfortunately, it's not just this one file that was
reported to me as unprintable. I use pdftops and
pdftocairo on my printservers, and a numer of other files
fail to print on Ricoh printers with the same "xyshow"
error, as mentioned in the bug. I hope we can debug it
until it is fixed both in pdftops and in pdftocairo. We
already made great progress. </div>
