Bug#1043331: cups: no color printing (black/white works; ppd file used)

[Uli Wannek <wannek-spamfree@gmx.de>]

Package: cups
Version: 2.4.2-3+deb12u1
Severity: normal
X-Debbugs-Cc: wannek-spamfree@gmx.de

Dear Maintainer,

   * What led up to the situation?
      Printing from graphical system or command line will always result in black/white/gray. 
      No color, independent of different settings or options.
      Color worked before (Debian buster), now upgraded to bookworm.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
      1) KDE print dialog, no matter if okular, libreoffice
         (color is default, explicitly chosen color)
      2) lp -o ColorModel=CMYK -d myprinter x.pdf 
   * What was the outcome of this action?
      the correct page in grayscale, but no color
   * What outcome did you expect instead?
      color
