Overview:

USB print behaves differently on devices with different OpenAPI versions. Based on the selected authentication method and OpenAPI version, the print from USB might be:

not supported
supported
supported with additional authentication screen shown on the panel

The additional authentication screen is an empty screen with title User authentication and two buttons OK and Cancel. The screen appears after a document from USB is chosen. To continue, click OK.

When using a combination of OpenAPI and authentication option for which the USB print is not supported, the additional authentication screen is displayed too, but the OK button is not enabled (it is greyed out and cannot be activated).
