Block ability to print in Smartforms Print Preview on SAP GUI for Java

Hi Gurus,

We found a error on Preconfigured Smart Forms, for Purchase Orders because we can print the P.O. on preview when the P.O. is not released, and we found a note 591576 - Ability to print in Print Preview (attached) where if you set the parameter "tdnoprint" on program the print on preview is blocked, but this works only for SAP GUI for windows, but in SAP GUI for Java we can print and save like PDF on the menu of PDF's preview (see the image), anybody know how block this function?

Thanks!
