Are you able to print any color pdf document in color print rather than grayscale using Adobe Reader and the same HP printer, or is the issue specific to a particualr document?
If latter is the case, could you please send the document to shilpi at adobe dot com?
Which HP printer are you using?
I'm having the same problem. It's not any specific document. It's any document. I'm using a x64 machine. I've tried different printers, upgraded printer drivers. Other x64 users are not having problems. Any suggestions?
Sorry, I guess I forgot to reply. I hooked my printer to my other computer and was able to print the document. This was a good resolution to my problem. I am getting ready to completely wipe the computer I've been having problems with so maybe when I download Adobe Reader after that it will be ok.
