[cups] cups Digest, Vol 5, Issue 10

[vivek kar]

Hi Helge,

Thanks for your information. I looked into the issue w.r.t filters and
found the following.
1) In debian based system, the same cups version is using the
following two filters to print a pdf file. It is printing fine.

   /usr/lib/cups/filter/pdftopdf
   /usr/lib/cups/filter/cpdftocps
.

2) In Linux based system like RHEL6_x64, the following filter is being
used only.

     /usr/lib/cups/filter/pdftops

    This filter does not support orientation request. Hence we are
facing the issue.

To make the Linux system behave same as Debian w.r.t filters, we did
the following experiment and found that both behaves correctly. The
following are done in RHEL6 x64 system which has cups 1.5.4.

1)  Placed the attached pdftopdf and cpdftocps filters in
/usr/lib/cups/filter/ directory.
2)  Placed the attached cpdftocps.convs and pdftopdf.convs in folder
/usr/share/cups/mime.
3)  chmod -fR 755 /usr/lib/cups/filter/pdftopdf
     chmod -fR 755 /usr/lib/cups/filter/cpdftocps
4)  Restart the cups service [ /etc/init.d/cups restart ].
5) Issues the lp -d <printQueue> -o orientation-requested=6
<fileName.pdf> and  lp -d <printQueue>  <fileName.pdf> .


This time it's printing ok.

But I wanted to know if there is any licensing issue with this
approach w.r.t the pdftopdf , etc filters.

Regards,
-Vivek
