How to know whether document is only printed or only viewed as print preview in SAP Script?

Dear All,

We have developed a script for cheque printing, and further requirement is to enable the user to print the cheque only once while he can preview it any number of times.

In Smartform we have control_parameters, output_options, JOB_OUTPUT_INFO, JOB_OUTPUT_OPTIONS, etc.

But, is there a way to find out if user has only done print preview or actually Printed the document in SAP script?
