Super weird! I have horizontal white lines appear on all jobs that are generated from imagePROGRAF Direct Print & Share (rendering the jobs to the Free Layout tool, where you can arrange and scale them prior to printing). This used to work very well!
I purchased and installed a new printhead.
I uninstalled the printer and all the associated software and then reinstalled the printer and associated software.
The white lines only appear from using imagePROGRAF Direct Print & Share. They don't appear if printing from Microsoft Word or Acrobat Reader directly to the printer.
I am a a loss!
Thanks so much for your help,
