iPrint for OES 2018
When uploading the HP Universal PCL 6 Driver version 6.6.5, no error is reported. However, the driver is not uploaded nor will it appear within the iManager Driver Store driver tab.
Upgrade the iPrint Client on the workstation uploading the printer driver to version 16.0.03 or newer.
HP changed a driver installation requirement of needing the driver name to match the printer name.
