Comments

This function will be fired from the printer driver. The user must implement this callback function in the user demo DLL. This callback function is required in order to be called by the printer driver, which will fire this function with the pPrintJobData that contains job specific data.

The user should fill the hUserData and uUserDataSize of the pPrintJobData once this callback is fired, then the pPrintJobData data will be sent automatically by the client printer driver to the server machine.

To obtain the data attached to the print Job ID in the server machine, call the L_PrnGetRemoteData function.

This function should be exported in the DLL module definition (def) file.
