printorganizer - resolution

Hi,

when I create a new set of prints, the resolution of the pdf is degraded:

the pltcfg is OK because:
if I select an other pltcfg, do an other print test, and go back to, the first pltcfg,
the resolution (pdf) is OK then

so  for printing I always have to make some drafts (?) befor I get the good ones

why are the first pdf's not good

direct printing with the pltcfg (without printorganizer) gives always good resolution
