To print from a Mobile device using SAPWIN, there are two sets of configuration that will need to be made, as follows:
Liquid UI Server Settings
In addition to the configurations in the Mobile device and in SAP, you must have the GuiXT Server deployed in order to print via SAPWIN. Printing directly to a client machine from the Mobile client device is not supported. However, no configuration on the Server is required to enable SAPWIN printing - the Server must merely be the intermediary between the device and the target printer.
