 Procedure documentation Optimizing SWIN Output Using SAPlpd Options Locate the document in its SAP Library structure

 Use

The SAPlpd transfer program contains options with which you can optimize printing speed or appearance of the output.

Procedure

...

       1.      Open SAPlpd.

       2.      Depending on the aim, activate or deactivate the following functions in the Options menu of SAPlpd:

 

Aim

Features

Improve the initial screen for SWIN output

Activate Color ® Use color. Even if the printer prints black and white, you obtain a better print screen.

Activate Graphic ® Print as Graphic

Background ® activate Print Background options

Increase printer speed for SWIN output

Activate Color ® Default.

Activate Graphic ® Print replacement characters or Do not print

Background ® deactivate Print Background options

 

Note

Downloading of graphics is another important factor in SAPlpd and PC print performance. In SAPscript, you can incorporate bitmap graphics and printer macros in forms. Downloading and processing these graphics takes extra time. If you set all SAPlpd options for speed and still have performance problems, check for graphics in your SAPscript print requests. You may need to eliminate these as well, or substitute smaller graphics for company logos and so on.

For more information about the individual options, see Using SAPlpd Options for SWIN Output.

Tracing SWIN Performance

SWIN print requests may print more slowly on a PC than print requests that use another device type, such as HPLJ4. This can be due to the following reasons:

·        With device type SWIN, Microsoft Windows performs the print formatting, while the SAP System performs the print formatting for printer-specific device types.

·        If you are using the access method S with the device type SWIN, the data transfer can take longer than the transfer with access method U, as the output data is transferred in blocks with the access method S.

You can check the performance in the SAPlpd window. Note the following message at the end of the request in the SAPlpd window:

Elapsed time <seconds> sec. (<seconds> sec. used by Windows)

The first figure is the total processing time for the print request.

The second figure is the amount of time that Microsoft Windows spent formatting the print request. Usually, this value is very small. However, in a few combinations of Microsoft Windows driver and printer, the processing time can be many seconds for a typical small print request.

If the Microsoft Windows processing time is too long, then you should try switching to the printer-specific SAP device type for this printer. Change the device type in the SAP definition of the printer:
