pdf - Print Colors Java -


how can configure awt-printerjob using specific printerservice print in colors?

my goal print pdf-file contains gray background colors. converted pdf pdfbox buffered image , set own printable class overwriting print method printerjob.

now if draw red rect within print method ignored. black rect printed.

when saving pdf-bufferedimage png file looks valid & good.
