Installed the iPrintAppliance as described in the paper. But a HP ColorLaserJet 3600DN in the Back for Printertests. With the Desktop-iPrint-client it works correct and fine.

then I activated emailprinting for this printer and installed as in the papers described the rendering maschine (english os, english office and so on.) When Iprint a document, i receive a mail back:
Subject: Job Notification (Printing Failed) :print printer=HPColor3600DN

Failed to print the job. Error occurred during document conversion.
Job List
Document: <name of document>
Status: Error in document conversion, or invalid page range. Supported document formats include Open Office, Microsoft Office, PDF, image and text files.

Has somebody an idea what is wrong?
