Starting SAPlpd 
The default path of SAPlpd is c:\Program Files\SAP\Frontend\SAPGUI\SAPLPD. You can create a shortcut to this directory to start SAPlpd. You can also start SAPlpd using command lines or navigate to the directory using Microsoft Windows Explorer.
You can start a shared version of the program over the network instead of installing the program locally on each of your PCs. If you do so, make sure that SAPlpd has a local, writable working directory on the PC. You can specify the location of the working directory in the Microsoft Windows program properties for SAPlpd.
You need to start only a single instance of SAPlpd on a Microsoft Windows PC. This instance of SAPlpd can accept output from any of your SAP Systems, if the Microsoft Windows printers are defined in more than one system. For example, you can use a single SAPlpd instance to accept output data from both your production and test SAP Systems.
You can also operate SAPlpd as a service under Microsoft Windows NT/Windows 2000. SAPlpd then runs on your PC even if no user is logged on. For more information, see SAP Note 42268 in the SAP Service Marketplace.
