Hallo David,<br>
<br>
I have tried all combinations of color models for my printer object and images
(indexed, rgb ),<br>
under unix and linux OS&nbsp; but the output is still gray.<br>
<br>
My question is: can the XPrinter option 'Generic(File Only') and EPSF selected
print colored <br>
graphic trees. If not, is there any posibility to save&nbsp; a &nbsp;graphics tree/view
to&nbsp; an eps file? <br>
<br>
Thanks! <br>
<br>
Milan<br>

I suspect you have a mismatch between the kinds of images
you want to send to the printer and the COLOR_MODEL you
chose for the printer. Or, the printer doesn't support
24-bit color images, and you will need to use a PALETTE
and a 2D image with the printer. Or, the printer driver
doesn't support color. If the latter, you might try using
the clipboard object to generate your EPS files.

Cheers,

David

I don't know how it is on UNIX, but in the Windows world
if your printer driver doesn't support color, you ain't gonna
get color output, no how, no way.

Have you tried the Clipboard, as I suggested earlier?

Cheers,

David
