Help me please.

This is a png file, which might not be supported completely in your Delphi version. Did you try to change it to a TcxImage which might be more compatible with the DevExpress printing system?

It also might be worth it to submit this issue to DevExpress if you can't fix it. They reply really quick and know more about their components then all of use here on SO :-)
