We've tried deleting all HP printers from the PC and then deleting the driver from the PC, but every time, it says that the driver is still in use. Our efforts to manually delete the drivers from the client PCs have been unsuccessful. We use the driver without the version in the name ('HP Universal Printing PS'), and so now the clients check in with the server, see that they have the identically-named driver with a newer version number, and do not download the older, working version from the server. There is an allow-list of print servers from which clients are permitted to download and install printer drivers.)
