Through SUPPORT on another group:


According to the information, it may relate to recent Windows Update in June 9, 2020. Lots of Designjet printers (and others) stopped working suddenly after the user's computer automatically installed Windows Update KB4560960. You can either uninstall the update or install the fix below:


Microsoft posted new updates in June 16~18, 2020 and mention that it may resolve the print issues.


First you should know which Operation System Version is.

Then you can choose one of the following links:

Win 10 2004                      :

Win 10 1903/1909          :

Win 10 1809                      :

Win 10 1803                      :


You can follow the instruction in the link and install the Windows Update.

One thing important:

According to the link,  “Windows Update and Microsoft Update” is not available and you may need to get the update from “Microsoft Update Catalog” .

Here is how to get it:

In that link you can find the “How to get this update” part.

In release channel chart, only “Microsoft Update Catalog” is shown as available.

You can click the link “Microsoft Update Catalog”  in the “Next Step” column of the second row and choose to download the update according to your operation system.
