As Michael explained, this is a limitation of the current design:

 * applications don't generate their own preview
 * applications can only generate the PostScript that is sent away as a 
   printjob (as requested by KDEPrint)
 * KDEPrint does not know in advance, if the target device is color capable
 * KDEPrint therefore always sends "color PostScript" (and let's CUPS and
   the target device handle the conversion to b+w if needed)
 * KDEPrint therefore also displays the printfile in color (calling a PS Viewer
   that is external to KDEPrint)

If I understand the reporter correctly, he wants it this way:

 - *IF* he explicitely requests a b+w job (to be sent to whatever printer,
   color-capable or not), *THEN* he asks for KDEPrint to request that b+w 
   data be generated by the application/Qt (which in turn would lead to a
   b+w preview as well, of course).

I *think* this is doable (*IF* Qt supports that... but I dunno if that's the
case).

Angelo, I don't think this can be implemented during the KDE 3.5.x lifetime
(3.5.6 will be out soon).

But we should keep it as a feature request for KDE4.
