What
is Spool Administration In SAP:
It is used to output the document to
a printer, fax, email and SMS etc.
It is only the process which is used to display the documents before they get printed.
Once a spool request is generated in the system, it can be printed to any printer with n no of copies, at any time.
Where as normal printing, the document will not be available once it is printed.
We can change the output format at any time.

Work process used for spool administration is
SPOOL 'S'
It is used to print the
documents to a printer or output to a fax machine etc. There should be at least
1 Spool process in the entire
system. It is also possible to configure more spool
process depending on the print/ spool volume
The spool process are configured by parameter ‘RDISP/WP_NO_SPO’
Depending on the resources as many no of spool processes can be configured.

How
to configure Frontend printer in SAP (SPAD):
- Go to transaction SPAD
- click on Display for Output Device (or choose
menu Configuration->Output Devices)
click on the change icon (or type F8)
click on the create icon (or type Shift-F1)
fill-in fields as needed
In First tab "Device Attributes"
- Output Device: any name starts with "Z"
- Device Type: SWIN or SAPWIN
In Second tab "Access Method"
- Host Spool Access Method: F: Printing on Front End
Computer
- Host printer: __DEFAULT
Please remember in above step its two times under-scope then DEFAULT
In the other tabs, please leave the default settings and press save which creates an output device
What
is SAP Spool process work flow
Step 1. A dialog user or a background process initializes a print
request.
Step 2. The print requests are stored in a location which is determined by a parameter ‘RSPO/Store_location = G’.........(G- Global directory at OS level) or
‘RSPO/Store_location = DB’......(DB- In database tables)
This location is referred as “Temse”( Temporary Sequential File).
‘Temse’ stores spool requests
Temse is stored in Global directory when it is referred as ‘G’. It is stored in database tables TST01 ; TST03. If it is referred as ‘DB’ .
By default the value is ‘DB’.
G: (Global Directory on Application Server):
1. If G is specified it is stored at OS level
2. The printing will be faster if there are less no of documents. Because from file system to spooler
The communication faster than database to host spooler
Advantages:
1. No special attention is required to backup the spool requests.
2. RDBMS rules are inherited to spool requests, because they are in the Database
Disadvantages:
1.A dedicated backup has to be planned to save the contents of Global directory.
2. When the records are more the printing consumes more time because of ‘Lack of indexes’ at file system.
Step 3 Spool process gets initiated and reads the contents from ‘TST01’ name of the Author, no of copies name of the printer and spool data from ‘TST03’. And converts spool requests into “Output Requests’ (Printer specific requests).
Step 2. The print requests are stored in a location which is determined by a parameter ‘RSPO/Store_location = G’.........(G- Global directory at OS level) or
‘RSPO/Store_location = DB’......(DB- In database tables)

Access
Methods in SAP Spool Administration
Types of Printing:-
1)Local Printing
1)Local Printing
2)Remote Printing
3)Front end printing
1) Local Printing:-If the spool server and the OS spooler on in the same system it is called the local printing.
2) Remote Printing:-If the spool server and the OS spooler are in different system
3) Front end Printing:- The printing with the SAP GUI

What
is Device Type in Spool / Printing administration of SAP:
A device type in the SAP System is
the category of printer to be addressed. When you define an output device,
choose the name of the device type that was defined in the SAP System for your
printer model, such as Post2 for a PostScript printer. The device type is the
total of all properties of an output device that the SAP System requires to
control the output device correctly, such as control commands for font
selection, page size, character set selection, and so on.
In most cases, the SAP System
already provides the appropriate device type for the printer type for the
printer model that you want to use. For a current list of the supported device
types, see SAP Note 8928 in the SAP Service Marketplace. The attachment for the
note contains most device types and can be downloaded. For information about
very specific device types, see the attachments of the relevant SAP Notes.
Most printers can also be controlled using a
generic format, that is, a device-independent format, such as PostScript. They
can be switched to a mode that is compatible with one of the standard printers
for which an SAP device type is available
The SAPWIN data stream is processed in the sapwin.dll component. The sapwin.dll component is also used by the new front-end printing, as described in SAP Note 821519. SAPWIN processing errors therefore affect both print methods. Patches for SAPSprint and the new front-end printing are available in SAP Notes 927074 and 841175 respectively.
