Spool Servers 
A spool server is a R/3 application server on which one or more spool work processes are running. Add the profile parameter
rdisp/wp no spo
to the instance profile of the relevant server (

Spool servers on the Devices / servers tab page, you can specify the following attributes and administration information for spool servers:- Server classification:
You can classify the spool server according to its intended use: Production printing, test printing, high-volume printing, and so. These classifications correspond to our recommendation for organizing the output architecture for optimum performance. The classification helps you to enforce your organization of printers as you define new printers.
- Alternate servers:
You can specify a "substitute" server for a spool server. The alternate server takes over the processing of output requests if the original server is down or unavailable. For more information, see
Alternate Servers.
- Logical servers:
To help you organize your printing architecture and manage printers, you can define logical servers. These let you, for example, define a spool server structure as the standard in one SAP System and transport the structure with only minimal changes to other SAP Systems. For more information, see
Logical Servers
- Load balancing:
You can specify whether the output processing workload of a server may be distributed among its alternate servers. By default, load balancing is inactive. Instead, the spool system assures that output requests are printed in the order that they are generated.
