Technically, the new front-end printing is based on controls that have been implemented in SAP GUI for some time. Controls are DLLs that run in the process context of SAP GUI. The new print control receives the print data and forwards them to the underlying operating system print system. If you are using the SAP GUI for Windows, you can also use the device type SAPWIN to use any printer with a Microsoft Windows driver. When printing with the SAP GUI for Java on other platforms, you need to use an appropriate device type, such as PostScript.
