A test print is a function that allows you to check the connection between the SAP system and the output device. If no spool request has been generated, it means that the test print was not sent to the spool system. One possible reason for this is that the device type of the output device is not compatible with the format of the test print. Therefore, you should check the assignment of the device type to the output device in transaction SPAD. The other options are not relevant for analyzing the issue, as they are related to the spool work processes, the application errors, and the host spooler, which are involved in the later stages of the printing process.
