What PDL are you using, we have had similar problems when selecting KPDL with the drivers for the Voyager models. If you need to have it on KPDL check to make sure that the "Allow Data Passthrough" box is unchecked or change it to PCL 5e and try the same print job.
Thanks guys, I have printed this out to bring over there.
Not sure what version of Adobe because the school is using a web-based grading service. The reports are generated in the web browser and appear to be PDFs.
Again a driver installed locally works fine, so I have time to explore all your suggestions..Thanks again!
