Historically, this was a problem; maybe that's fixed or partially fixed now. gv is just using lpr/lp to print. So, if for example you print the file directly with "lpr -P printer $file.ps", is it still monochrome? This will eliminate gs, in case it's causing the problem. When you print from the GIMP, are you using the regular Print dialogue, or are you using the "Print with Gutenprint" dialogue (gimp-gutenprint)? The former prints via the normal printing system (as if you did it with lpr), and sends either the pixmap or the pixmap embedded in PostScript to the print queue. The Gutenprint dialogue does all the rendering inside GIMP and sends raw printer commands to the queue (lpr -o raw). If the printer is misconfigured in CUPS, that could explain why it works from the GIMP. It doesn't explain OpenOffice though. Regards, Roger -- .''`.
