You can print or fax any type of R/3 output (lists and SAP forms) on a SWIN printer or fax machine. However, the following restrictions apply:
- Output using the device type SWIN usually takes longer than printing using a printer-specific device type, as the output is processed by the Windows printer driver.
- Bar code printing is possible only if an appropriate dynamically linked bar code library (.DLL) file is available in the Microsoft Windows system. This restriction applies even if the printer has a bar code cartridge, because Microsoft Windows cannot pass the required print commands to the printer.
- SWIN cannot print all of the graphical objects used by the SAP System.
It can print R/3 symbols (the SAPDings font). Likewise, SAPlpd can print TIFF and Windows/OS2.BMP bitmap graphics that have been uploaded into SAP forms. TIFF graphics are converted into Windows.BMP bitmaps for printing.
It cannot print the following:
- PostScript, Prescribe, or PCL-5 printer macros that have been uploaded into SAPscript. To print these macros, you must use the printer-specific device type.
- R/3 presentation graphics. These graphics require that the printer be defined with one of the graphics drivers delivered with the SAP System.
