           Summary: Poppler cannot handle certain font encodings or font
                    types correctly
           Product: poppler
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: cairo backend

The LaTeX source file

If I use the T1 fonts in LaTeX, Evince cannot print the PDF files any more.
Actually printing takes very long and outputs a rastered image. With the Adobe
Reader everything works fine. In the related Ubuntu bug report
(https://bugs.launchpad.net/ubuntu/+source/evince/+bug/227186), Sebastian
Bacher asked to open a bug report for poppler. Actually I'm not sure, whether
this is a bug in poppler or in cairo. There is another related bug report in
Launchpad (https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/150187).

Here are the details:

I created a small sample LaTeX file (test.tex), which demonstrates the bug. If
I compile it without the "fontenc" package using pdflatex, everything works
fine in Evince. I named this PDF file "good.pdf". If I compile it with the
"fontenc" package (and the option "T1", which uses fonts of a certain LaTeX
font encoding), pdflatex creates a PDF file ("wrong.pdf") that Evince cannot
print correctly any more. I also attach the printing output of Evince, when
using the PDF printer. I named these file "good.printed.pdf" and
"wrong.printed.pdf".

The following graphic illustrates the described setting.

Since the problem is somehow related to fonts, I also compile the font
information of pdffonts and the Adobe Reader in the following:

Evince states version 2.22.2 with poppler 0.6.4 (cairo). It's the Ubuntu 8.04
package. If you need any more information, I'd be glad to help.

Sincerly, Simon
