HP DeskJet 670C: no color printing

[Ralf Hildebrandt <Ralf.Hildebrandt@xxxxxxxxxxxxxxxxxxxxx>]

Printer: HP DeskJet 670C
System: Debian unstable
Kernel: 2.4.8

Installed Software:

apsfilter      6.1.1-6        Magic print filter with automatic file
type 
gs-aladdin     6.50-5         Postscript interpreter with X11 and
svgalib
gsfonts        6.0-2          Fonts for the ghostscript interpreter
lprng          3.7.4-5        lpr/lpd printer spooling system

Using the SETUP tool I specified "hpdj" and "dj670c".

Result: The printer only prints in black&white/gray; test.ps is also
printed correctly, but in b&w.

When still using gnu-gs 5.50 instead of aladdin-gs, I had color output.
