Printing help (Creo 3)

We have an older E-size printer - the HP DesignJet T1200, but it's still kicking.

One of the problems is that the prints we send to it turn out in grayscale.

Does anyone know what settings to use so that they turn out in color?

I tried using plotters POSTSCRIPT, DESIGNJET600, COLORPOSTSC, all do the same monochrome output.

Maybe I have to go through the MS print manager?  The PDFs I print from Acrobat Reader on this printer do come out in color, so that might be it...

Anyway, this is the PCF file:

PLOTTER DesignJet

BUTTON_NAME C - HP DesignJet T1200(XYZP0006)

BUTTON_HELP Front Office - near entrance

PLOTTER_COMMAND print /d:\\XYZfileserver3\XYZP0006

PEN_TABLE_FILE C:\PTC-Apps\Plotter\pnt\hpdj_t1200.pnt

PAPER_SIZE C

PLOT_SCALE fit_paper

PLOT_WITH_PANZOOM no

PLOT_NAMES yes

ALLOW_FILE_NAMING yes

DELETE_AFTER_PLOTTING yes

PLOT_TRANSLATE 1.000000 0.500000 default

and this is the pnt file:

pen 1 thickness .015 IN; edge_highlite_color attention_color section_color;

pen 2 thickness .008 IN;

pen 3 thickness .008 IN;

pen 4 thickness .012 IN;

pen 5 thickness .012 IN;

pen 6 pattern 1 IN ; thickness .012 IN;

pen 7 pattern .06 .06 .06 .06 IN;thickness .009 IN;

pen 8 thickness .010 IN;

is there a config.pro setting that I'm missing?

many thanks in advance for you print gurus.
