reg: Suppress Print popup while printing ALV

Hi Experts,

I am using FM REUSE_ALV_LIST_DISPLAY to print the report and convert the spool to PDF and email it as attachment.

When iam calling the FM for printing by passing parameter IS_PRINT, it is asking me to enter printer details as popup. I need to suppress this popup. I tried passing the default print parameters to this IS_PRINT, but still no result.

Can anyone help me on this.

Thanks

Naveen
