Sometimes a TppImage with a JPG prints BLACK

rbuser

Windows XP, RBuilder 7.01 Professional and an OKI C5100 printer.

I have a report with a JPG embedded in a TppImage, and sometimes it prints a
black rectangle.

I don't know why does it work this manner. For example, if I execute 20
times the ppReport.Print, I can get some of them black aleatorily.

Thank you.
