Unit 10: Including Printers in SAP Systems ADM100
• Value G: Stored at operating system level in global directory
(Advantage: performance).
Note: You can also specify the storage location individually for the
output device in transaction SPAD (menu pathEdit → Data Storage).
SAP Note 20176 contains additional possible values for rspo/store_location.
The creation of an output request prompts the SAP spool system to send
a (usually) printer-dependent, completely formatted data stream to a
printer using an operating system spooler (OS spool). This means that the
addressed printer model must be known to the SAP system. Definitions of
this type are described as device types.
If a printer cannot be controlled at operating system level, it cannot be
used from the SAP system, either.
There are many ways in which a spool work process can reach an operating
system spooler. The most important of these connections, described as
access methods, are introduced in the following sections.
Local Printing
Access methods are used to describe how the spool work process is
connected to with the operating system spooler. Local printing simply
means that the spool work process is communicating with a spool system
on the server on which it is running “itself”. This means that no network
communication between the spool work process and the operating system
spooler is required. The local printing access method therefore has NO
meaning with regard to the location at which the output is printed onto
paper. The local printing access method is obviously also a very quick type
of connecting the processes involved. We recommend that you read SAP
Note 108799 as part of your preparation.
