ADM100 Lesson: Configuring Printers in SAP Systems
Figure 112: Local Printing
Acharacteristicoflocal printing is that the spool work process and
operating system spool are running on the same host. Itisirrelevant
whether the printer is directly connected to this host, or is reached over
a network (and possibly another print server). The spool work process
passes on its data “locally”, that is on the same host.
• On UNIX systems, the print data with access method L is output
using operating system methods (for example, with the commands lp
or lpr). The specific syntax is stored in profile parameters.
• Under Microsoft Windows, the data with access method C is passed
directly to the operating system print API.
Local printing is the fastest and most reliable connection from the SAP
system to the operating system. As soon as the spool work process has
transferred its data, it can deal with new output requests - even if the
operating system spooler may still be occupied.
You can configure multiple spool work processes for an SAP instance.
This has - irrespective of the access method - consequences for the output
sequence. Differentspoolrequestsforthesameprintermaybeprinted
in a different order to that in which they were created. If you require
output in sequence, you can specify this for individual printers. However,
a setting of this type reduces the ability to process in parallel. For more
information about this topic, see SAP Note 108799.
