Hi,
it took me quite a bit of time to figure out the various problems of
the newer poster versions (>=2002). The 1999 version (as shipped by
Debian) works more reliably as well for me (using, e.g.,
dvips-generated postscript). Unfortunately, the kdeprint dialog is
messed up (missing '-F' option), but one can still successfully use
the poster printing feature from within kdeprint!
Nevertheless, I did some work and created a poster package for version
20050907 with a few patches applied to it that, AFAICS, resolve the
bugs mentioned in the earlier posting by Peter. I could, for instance,
successfully check that #255718 is still fixed with it. Earlier patches
(libpaper, etc.) are also included.
The multi-page feature introduced in the 2002 version explicitly
counts "%%Page:" lines to select pages to print. This breaks printing
of posters produced with latex and dvips containing embedded EPS
figures. Although those postscript files are probably not
DSC-compliant, I am sure many Debian users (not only me) want to print
such (non-compliant) files. Therefore, I also included a patch that
disables the page counting (see lines 1032ff). This unfortunately
breaks multi-page printing.
I attach the patch to poster.c and send you, Peter, a adapted source
package.
cheers,
Daniel
