I printed the only the first page of the document to 'test.ps' file and I found the
followings:
$ cat test.ps |/usr/bin/gs -r600 -g4958x7016 -q -dNOPROMPT -dSAFER -sDEVICE=ppmraw -sOutputFile=- -| /usr/local/bin/cifmp160 --imageres 600 --papersize a4

$ echo $?
1
This means that 'gs' will exit with exit code 1 in case of error, however, 'cifmp160'
will exit with exit code 0 in case of an error. The following can be read in bash(1),
chapter "Pipelines":
> The return status of a pipeline is the exit status of the last command, unless the
> pipefail option is enabled. If pipefail is enabled, the pipeline's return status

This means that the exit code of the full pipeline will be zero, but there was some
commands which failed in the pipe!
