A spool request contains information on the data to be output, its formatting, and the printer model used. The spool request generated is stored in the TemSe (Temporary Sequential file table).

Hint: Spool requests can be created by dialog work processes or by background work processes. Spool work processes do not create spool requests.
In an SAP system, the connection between a spool work process and the operating system spool process is known as the .access method.
